Conditioncheck

This is the code contribution for a new procedure, Condition Check.  Please see http://wiki.collectionspace.org/display/collectionspace/Object+Condition+Checking+and+Technical+Assessment+Schema for schema and other details.
This code contribution is based on an older v2.6 stack as this is the version of CollectionSpace currently in use at MMI. 

I'm concerned about the added past commits in this pull-request. This code contribution started off months ago from a v2.4 stack and has been updated (merged) with every new release through v2.6. It doesn't appear to be anything out of place.
