Modified Catalog to store generated DDL rather than the original DDL that the Catalog was compiled from. Added Class to convert Catalog state into DDL syntax. Extended existing compiler tests to compare the generated DDL with regenerated DDL compiled from the generated DDL to verify DDL consistency.
Additional cleanup found during review.
Remove unnecessary debug code.
Move DDL output to file called autogen-dll.sql in Catalog.Jar. Comment PARTITION PROCEDURE statements in generated DDL when the Java Procedure has an annotation.
Additional files belonging to last commit.
There are still paths that don't annotate a procedure.
Implement DDL Generation based on Catalog and include with jar.
