Tracking how egrmaclean affects summary stats

[Alexandersax]

Find change in ORF, CLPM, CLSPM, etc between versions 1 (pre egrmaclean), 2 (old egrmaclean), and 3 (new egrmaclean).
Make these changes into a table.

EDIT: MICHAEL: Michael will develop tables to report back on N and % of kids who are zero or missing. These old databases in which zeros were recorded to missing for an entire section to change them back to zero are the ones to looks at. In these cases we believe we had training issues and assessors decided kids could not read without giving them a chance.

EDIT: MICHAEL: What do we do about correcting old data reports? Michael will develop tables comparing output from old to new and we will decide whether to egrmaclean the old stuff, or not
