clean up the code side of contracts and grants collection activity document stuff
I think this could/should probably be removed as well. It looks like the only remaining required usage is for the lookedUpCollectionName for the mult-value lookup in contractsGrantsCollectionActivityAwardsInformation.tag - couldn't that just be changed to something else (like invoiceDetails) - of course I probably don't understand the multi-select mechanism. Regardless, there is a related constant that should be removed.
