transcript.start_time is a float not an integer
build indexes with pager unless DEBUG=1 is on
zap un-needed debugging code
make start_time a double for those extra long audio assets; flip to_indexed_json (returns json) and as_indexed_json (returns object); NOT SURE ABOUT THIS: explicit add of date_created, date_broadcast, date_added to index, to avoid ES exceptions on un-found field when reaping facets (index_name for date_added in particular seems to be ignored (buggy))
