# ROUTINE

#
# DESCRIPTION
#   this routine will left-pad the entry-id with
#   zeros out to the appropriate number of place (15 max)
#   depending upon if your prefix your entry-id's with
#   anything
#
# RETURNS

# ROUTINE
#   ars_decodeStatusHistory(field-value)
#
# DESCRIPTION
#   this routine, when given an encoded status history field
#   (returned by GetEntry) will decode it into a hash like:
#
#   $retval[ENUM]->{USER}
#   $retval[ENUM]->{TIME}
#
#   so if you have a status field that has two states: Open and Closed,
#   where Open is enum 0 and Closed is enum 1, this routine will return:
#
#   $retval[0]->{USER} = the user to last selected this enum
#   $retval[1]->{TIME} = the time that this enum was last selected
#
#   You can map from enum values to selection words by using 
#   arsGetField().
