+ Decode literal, length, and distance codes and write out the resulting

+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for

+
+ - The maximum input bits used by a length/distance pair is 15 bits for the

+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm.avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm.avail_out >= 258 for each loop to avoid checking for

+ Process a set of code lengths to create a canonical Huffman code. The

+ symbols by length from short to long, and retaining the symbol order
+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the
+ decoding tables are built in the large loop below, the integer codes
+ are incremented backwards.
+
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that

+
+ The codes are sorted by computing a count of codes for each length,
+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+
+ The length counts are used for other purposes as well, i.e. finding

+ codes at all, checking for a valid set of lengths, and looking ahead
+ at length counts to determine sub-table sizes when building the

+
+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+The list above is updated frequently, new crypto markets, exchanges, bug fixes, and API endpoints are introduced on a regular basis. See the [Manual](https://github.com/ccxt/ccxt/wiki) for more details. If you can't find a cryptocurrency exchange in the list above and want it to be added, post a link to it by opening an issue here on GitHub or send us an email.
+
+The library is under [MIT license](https://github.com/ccxt/ccxt/blob/master/LICENSE.txt), that means it's absolutely free for any developer to build commercial and opensource software on top of it, but use it at your own risk with no warranties, as is.
+

+
+## Install
+
+The easiest way to install the CCXT library is to use a package manager:
+
+- [ccxt in **NPM**](https://www.npmjs.com/package/ccxt) (JavaScript / Node v7.6+)
+- [ccxt in **PyPI**](https://pypi.python.org/pypi/ccxt) (Python 3.5.3+)
+- [ccxt in **Packagist/Composer**](https://packagist.org/packages/ccxt/ccxt) (PHP 5.4+)
+
+This library is shipped as an all-in-one module implementation with minimalistic dependencies and requirements:
+
+- [`js/`](https://github.com/ccxt/ccxt/blob/master/js/) in JavaScript
+- [`python/`](https://github.com/ccxt/ccxt/blob/master/python/) in Python (generated from JS)
+- [`php/`](https://github.com/ccxt/ccxt/blob/master/php/) in PHP (generated from JS)
+
+You can also clone it into your project directory from [ccxt GitHub repository](https://github.com/ccxt/ccxt):
+
+```shell
+git clone https://github.com/ccxt/ccxt.git
+```
+
+### JavaScript (NPM)
+
+JavaScript version of CCXT works in both Node and web browsers. Requires ES6 and `async/await` syntax support (Node 7.6.0+). When compiling with Webpack and Babel, make sure it is [not excluded](https://github.com/ccxt/ccxt/issues/225#issuecomment-331905178) in your `babel-loader` config.
+
+[ccxt in **NPM**](https://www.npmjs.com/package/ccxt)
+
+```shell
+npm install ccxt
+```
+
+```JavaScript
+var ccxt = require ('ccxt')
+
+console.log (ccxt.exchanges) // print all available exchanges
+```
+
+### JavaScript (for use with the `
+```
+
+Creates a global `ccxt` object:
+
+```JavaScript
+console.log (ccxt.exchanges) // print all available exchanges
+```
+
+### Python
+
+[ccxt in **PyPI**](https://pypi.python.org/pypi/ccxt)
+
+```shell
+pip install ccxt
+```
+
+```Python
+import ccxt
+print(ccxt.exchanges) # print a list of all available exchange classes
+```
+
+The library supports concurrent asynchronous mode with asyncio and async/await in Python 3.5.3+
+
+```Python
+import ccxt.async_support as ccxt # link against the asynchronous version of ccxt
+```
+
+### PHP
+
+[ccxt in PHP with **Packagist/Composer**](https://packagist.org/packages/ccxt/ccxt) (PHP 5.4+)
+
+It requires common PHP modules:
+
+- cURL
+- mbstring (using UTF-8 is highly recommended)
+- PCRE
+- iconv
+- gmp (this is a built-in extension as of PHP 7.2+)
+
+```PHP
+include "ccxt.php";
+var_dump (\ccxt\Exchange::$exchanges); // print a list of all available exchange classes
+```
+
+### Docker
+
+You can get CCXT installed in a container along with all the supported languages and dependencies. This may be useful if you want to contribute to CCXT (e.g. run the build scripts and tests — please see the [Contributing](https://github.com/ccxt/ccxt/blob/master/CONTRIBUTING.md) document for the details on that).
+
+Using `docker-compose` (in the cloned CCXT repository):
+
+```shell
+docker-compose run --rm ccxt
+```
+
+You don't need the Docker image if you're not going to develop CCXT. If you just want to use CCXT – just install it as a regular package into your project.

+## Documentation
+
+Read the [Manual](https://github.com/ccxt/ccxt/wiki) for more details.
+
+## Usage
+
+### Intro
+
+The CCXT library consists of a public part and a private part. Anyone can use the public part immediately after installation. Public APIs provide unrestricted access to public information for all exchange markets without the need to register a user account or have an API key.
+
+Public APIs include the following:
+
+- market data
+- instruments/trading pairs
+- price feeds (exchange rates)
+- order books
+- trade history
+- tickers
+- OHLC(V) for charting
+- other public endpoints
+
+In order to trade with private APIs you need to obtain API keys from an exchange's website. It usually means signing up to the exchange and creating API keys for your account. Some exchanges require personal info or identification. Sometimes verification may be necessary as well. In this case you will need to register yourself, this library will not create accounts or API keys for you. Some exchanges expose API endpoints for registering an account, but most exchanges don't. You will have to sign up and create API keys on their websites.
+
+Private APIs allow the following:
+
+- manage personal account info
+- query account balances
+- trade by making market and limit orders
+- deposit and withdraw fiat and crypto funds
+- query personal orders
+- get ledger history
+- transfer funds between accounts
+- use merchant services
+
+This library implements full public and private REST APIs for all exchanges. WebSocket and FIX implementations in JavaScript, PHP, Python are available in [CCXT Pro](https://ccxt.pro), which is a professional addon to CCXT with support for WebSocket streams.
+
+The CCXT library supports both camelcase notation (preferred in JavaScript) and underscore notation (preferred in Python and PHP), therefore all methods can be called in either notation or coding style in any language.
+
+```JavaScript
+// both of these notations work in JavaScript/Python/PHP
+exchange.methodName () // camelcase pseudocode
+exchange.method_name () // underscore pseudocode
+```
+
