Fix display of representedCustodianOrganization in QRDA Cat III

It appears that the tag_name variable in the _organization template
was not working properly. For the assignedCustodian, the element name
is supposed to be representedCustodianOrganization but it was using
the default of representedOrganization. This change removes the
default value and passes in the tag name with each call to the
partial.
add a schema validation test for cat-3 exports
drop extraneous <id/> element from <assignedCustodian/>

Starting work on prefilters for the CQM calculation M/R jobs

This code attempts to look at the measure structure to come up with
a MongoDB query to prefilter records before doing measure calculation.
Currently, this will only work for measures with birthdate criteria
specified in the IPP relative to the measure period. This will require
work in QME to take advantage of the prefilters.
Now building the MongoDB query hash in the measure model
Flip comparitors (they were wrong), removing $and clause (not needed)
