docs: Given a COBOL copybook, produce a set of java classes (source code) used
  to convert mainframe data (matching the copybook) at runtime.
  
  @param cobolSource the COBOL copybook source
  @param targetPackageName the java package the generated classes should
  reside in
  @param xsltFileName an optional xslt to apply on the XML Schema
  @return a map of java class names to their source code
