# CT:  A few notes for future refactoring of this code:
# 1:  I don't think it is a good idea to make the UI too dependant on internal
#     code structures but I don't see a good alternative at the moment.
# 2:  CamelCasing: -1

=item payment

This method is used to set the filter screen and prints it, using the 
TT2 system. (hopefully it will... )
