Class Manager: Auto-load classes based on XML definitions

Class Manager can be used to load classes based on classpath definitions read from XML files. Including the source files will be automatic, and transparent to the application.

Classpath xml files can be used to specify paths from which given classes should be loaded. They can also specify source filename templates and lookup paths for automatic lookup.

Offers features for validating class paths: can check if source files exist, detect class name collisions, includes all source files to find compiling errors, etc.
