IP/MAC is the type of address followed by a "%" and
then the MAC or IP address , notice no leading 0's on
the MAC same format we enter from the GUI now.

INTERVAL can be MON,DAY or HOUR that is how long we
count bytes for this user before starting over

WARN1 is the first byte count limit, we take action
when this user has moved this many total bytes in and
out, WARN1 it has the following subfields seperated by
"%"

   the number of bytes needed to set off this warning
(bi-directional total)

   the email of the person to send a memo to

   the text of the e-mail

   and the last number is the kbs to set a limit to
for this user.

WARN2 just like WARN1 a second level of warning.
