First attempt to write a test that verifies if ProxyManager will crash with defined classes
Minor docblock fixes/clarifications
Minor docblock fixes/clarifications
Adding tests for lazy loading value holder instantiation with all defined classes
Adding tests for null object instantiation with all defined classes
Using the raw code generator in tests
Mapping over existing classes and generators instead of manually defining single tests
Removing limits over declared classes list - now testing all declared classes
Skipping `final` classes when generating proxies: throwing an exception instead.
Skipping over non-test-asset classes that are found in the project, allowing not found classes
Passing `-n` as parameter (should run without extensions)
Remove duplication of interfaces
Turn interfaces unique on collection
Generate abstract methods to be compliance with method signatures
Fix abstract methods inheritance
Fix interfaces implements

- Remove uncessary namespaces from AbstractMethod
- Put `NullObjectGenerator` to be generated with abstract methods
  implementation
Remove debug line of code
Remove call to `setBody()` with a empty string

- Put some annotations on methods of ClassGeneratorUtils
Update namespaces, remove alias for ClassGenerator
Modify name of "createCollection" to "buildConcreteMethodsFromOriginalClass"
