+ Eliminated BeanDefinitionRegistrar and BeanRegistrar types
+ Simplified ConfigurationEnhancer logic
+ Updated JavaDoc for ConfigurationModel and related classes
+ Updated JavaDoc for all ASM visitors

+ Updated all projects to use the re-introduced org.springframework.asm instead of org.objectweb.asm (.java, template.mf, ivy.xml, and .classpath files have been updated)
+ Finished support for @Import, including detection of circular imports

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

+ 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

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.
