Description

I want to be able to test parsing and be able to profile a standalone parse and WALProcedureStore load of procedures. Adding a simple main on WALProcedureStore seems to be enough. I tested parsing it a dir of hundreds of WALs to see what is going on when we try to load. Good for figuring how to log, where the memory is going, etc., in this subsystem.
