Code generators

This is a collection of Symfony 2 code generators based on nikic's PHP-Parser. These generators can be way more flexible than the ones provided by SensioGeneratorBundle due to their event-based nature., _(*1)

First, all generators utilize an event dispatcher to notify others of the changes. This allows automatic tests/specs generation once a base generator has fired., _(*2)

Here the ControllerGenerator dispatches a ControllerGenerated event which then triggers TwigViewGenerator and UnitTestGenerator to generate tests and Twig templates., _(*3)

Second, an AST processor dispatcher is built in. You can hook up your own ProcessorInterface implementations that would modify the syntax tree before it's dumped into a file., _(*4)

Currently, the implementation is lacking some things:, _(*5)

~~PHPParser does not yet allow dumping comment blocks, so there's no way to generate annotations yet.~~
The ControllerGenerator is mostly just proof-of-concept.
AST processors have not really been tested yet.
Everything needs way more flexibility.
