# NcModelAvailableTimesQuery
#
# This code has been developed by the SIB for use in the AWIPS2 system.
# Scans dataLocation directory and returns all the available cycles.
#
# Usage:
# import NcModelAvailableTimesQuery
# query = NcModelAvailableTimesQuery.NcModelAvailableTimesQuery()
# query.setDataLocation("$MODEL/gfs")
# query.setCurrentCycle("2010-11-28 18:00:00.0")
# return query.execute()
