Phap PHP has another parser

Release 0.6.0

This release says goodbye to the OOP programming interface. It’s been an awkward fit for a combinator library. It has also proved to be too much work to maintain docs and tests for two interfaces with nothing but aesthetic benefit.

I have also renamed the or and and functions to alternatives and sequence respectively. This should help to retain the natural language flow found in the OOP interface. It also brings our vocatulary more in line with other ecosystems.

The end function has been reconfigured to not take a parser as input. Use it with sequence

I have also added more example code in the tests/Integration folder. This includes an example of matching paremtheses (context free grammar) along with a more elaborate example in the form of a json parser.
