Adding loading measure via hqmf documents.
This commit allows a user to upload a measure in hqmf format. As part of the loading process the
value sets required by the measure will be downloaded and added to pophealth.  If a measure is an
episode of care measure the user will be prompted to select the data criteria to use as the episodes.

This also supports flagging a measure for which a lower outcome from the measure is considered to be better as
well as updating a measures category.
