Adding application of EM_COINC label to all relevant events (GW and EM) whenever any coincident event is identified.

Adding an extra column to the output of raven_fetch_external_triggers that includes the trigger ID of a GRB as originally assigned by the spacecraft that discovered it. This will make it easier to check against the GCN webpage.

Adjusting the combined rate of independent Swift and Fermi GRB discovery to 0.807 per day, reflecting the results of an analysis I did on Swift and Fermi bursts dating back to the launch of both satellites. (The error on this inferred rate is about 2.5% based on 2108 bursts between 14 August 2008 and 31 August 2015.) Scripts and data files from NASA HEASARC are also added in this commit. The results of this analysis will be included in the RAVEN methods paper.

Adding a script that automates checking of the local file cache of GCN notices. (This is Mark Poe's first commit.)

GraceDb queries now support float-type GPS times, so this commit fixes RAVEN so that it uses the full real-valued GPS time of a trigger to search around. It also removes dependence on lal.gpstime.tconvert from raven.gracedb_events.

Removing the --xml option from raven_coinc_search_gracedb because it is no longer used; also replacing checks for required command-line arguments with a much simpler check for all of them at once

Final cleanups on all files; bumping version number to 1.0 (includes time coincidence only and runs in production)

Removing dependence on the VOEvent XML file for GRBs; instead, now inheriting all properties directly from GraceDb

Adding a script to do web scraping on the Swift and Fermi GCN notice tables, locate triggers within a user-specified time window, and package associated information (trigger no., date, time, notice type, RA, dec, and error radius) into a CSV table.

Adding a script, raven_fetch_external_triggers, that will retrieve all external triggers within some user-specified pair of UTC dates from GraceDB and store them in a CSV table. (Written with Mark Poe.)

Replacing dependence on lalinference.fits.iso8601_to_gps with dependence on lal.gpstime.tconvert; updating import of lalinference.fits from the deprecated lalinference.bayestar.fits

Adding sanity checks on the time coincidence window in both raven_coinc_search_gracedb and raven.search.query().

Renaming the --direction flag as --trigger, and renaming its arguments from the confusing forward/backward convention to the more explicit 'exttrig' and 'gw'

Removing variables for start- and end log messages in raven_coinc_search_gracedb; instead, just putting these strings in the function calls directly.

Massive clean-up of raven_coinc_search_gracedb: Eliminating duplicate loops, adding search window parameters as command line arguments, checks for these arguments, and consistency with the new structure of the raven.gracedb_events and raven.search modules.
