Class discovery

This package provides components and abstractions to help with all kinds of discovery operations across php class files.

Main concepts:

• ReflectionClassesIA*:
  IteratorAggregate that lists a special type of \ReflectionClass class objects.
  Typically this is based on a ClassFilesIA* object.
• FactoryReflection*:
  Interface for custom ClassReflection and MethodReflection, with methods that treat both of them as "factories".
• FactoryInspector*:
  Inspects a classes or methods, to find whatever you might be looking for.
• Discovery*:
  IteratorAggregate to discover objects found by an inspector in reflection methods.
