##
# Create a new raid schedule or update an existing one.
# The raid will be owned by the given +current_guild+.
#
# A raid needs a location (+where+), a date (+raid_date+),
# a start time (+raid_time+) and optionally a hash of +roles+
# to define the types of characters needed in this raid.
#
# The start time for a raid by default is 15 minutes before the
# start time. This will eventually be configurable.
#
# To update an existing raid with new information, use
# +current_raid=+ to set that raid.
