BitArray for PHP.

This project manipulates compact array of bit values stored internally as strings.

The bit arrays may have variable length specified when an object is created using either:

* a specific size;

* a traversable collection;

* a string representation of bits;

* a json representation of bits;

* a slice from another bit array;

* a concatenation from two others bit arrays.

The project provides methods to get and set bits values using PHP natural syntax as well as the iterator facility offered by the PHP `foreach` language construct.

It also provides methods for bitwise logical operations between two bit arrays `and`, `or`, `xor` and the `not` operation.

This project uses:

* [PHP Code Sniffer](https://github.com/squizlabs/php_codesniffer) for checking PHP code style
