=item display_report($self, $request, $user)

Renders out the selected report given by the incoming variable report_id.
Returns HTML, or raises an error from being unable to find the selected
report_id.

Renders out a list of meta-reports based on the search criteria passed to the

Meta-reports are report_id, date_range, and likely errors.
Search criteria accepted are 
date_begin
date_end
account
status

=item correct ($self, $request, $user)

Requires report_id, entry_id.

Correct is a strange one. Based on the type of transaction listed in the
report, it will run one of several correction functions in the database.
This is to prevent arbitrary editing of the database by unscrupulous users.
