+Addition of a drain_capable flag indicating how many groups of 30 days
+can be drained.  Above example shows 90-119 days remaining.
+
+=head2 drain ( session_id, building_id[, times] )
+
+Allows draining of an evein quickly.  Instead of 4e per day over 30 days,
+this will use up 30 days and provide 30e instantly.  The optional C<times>
+parameter allows draining of multiple months' worth in a single RPC.  Periods
+less than 30 days cannot be drained quickly.
