Refactored Assay to store experiment, project, target objects, rather than ids
Updated assay resource to avoid generating expanded json since we have all the fields already
Added db method to search of entity ids (and not retrieve full entities)
Updated /assays to only query for entity ids rather than full entities if expand=false or null
Update the table used for compound syn queries. Used to be synonyms. Now we use synonym_type
Merge branch 'master' of github.com:ncats/bard
