/**
* INTERNAL:
* <p><b>Purpose:</b>The purpose of this class is to act as an entry point into the
* TopLink JAXB 2.0 Generation framework
* <p><b>Responsibilities:</b><ul>
* <li>Run initial processing on a list of classes to create TypeInfo meta data</li>
* <li>Provide API to generate Schema Files</li>
* <li>Provide API to generate a TopLink Project</li>
* <li>Act as an integration point with WebServices</li>
* </ul>
* <p> This class acts as an entry point into JAXB 2.0 Generation. A Generator is created with a
* specific set of JAXB 2.0 Annotated classes and then performs actions on those, such as
* generating schema files, or generating TopLink Projects. Additional information is returned
* from the schema generation methods as a means of integration with WebServices.
