  RT::Transactions - a collection of RT Transaction objects

=head1 DESCRIPTION


=head1 METHODS

=head2 LimitToTicket TICKETID 

Find only transactions for the ticket whose id is TICKETID.

This includes tickets merged into TICKETID.

Repeated calls to this method will intelligently limit down to that set of tickets, joined with an OR
