+ Consolidated all remaining supporting classes into .support package, eliminating .internal.*
+ 7 public types remain

+ Removed @FactoryMethod indirection and extension point in favor of direct processing of @Bean annotations

+ Adding POC tooling integration points, namely AbstractConfigurationPostProcessor and allowing for tooling-specified ClassLoader for use with ASM parsing
+ Eliminated ModelMethod in favor of BeanMethod throughout

+ callbackType -> interceptor
+ registrarType -> registrar
+ validatorTypes -> validators

Initial cut at migrating JavaConfig essentials into Core. test.basic.BasicTests successfully excercises the simplest possible @Configuration class (contains a single @Bean method). 39 classes were pulled in from from JavaConfig to support this use case.
