Fixed some issues with the "is_step" for this part of the expert, and added two more operations (manage/build/finalize) for newstacksize and newstackindex.  No idea if this works, but will figure that out soon.

Could use some more commenting.

Added fixme for when an operation is called to check to see if we should call super or not.

Will need to make a test case and run this to see if this will even work.
