=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.

=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.

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

Creates a new report, from a selectable set of bank statements that have been
received (or can be received from, depending on implementation)

Allows for an optional selection key, which will return the new report after
it has been created.

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

Requires report_id

Approves the given report based on id. Generally, the roles should be 
configured so as to disallow the same user from approving, as created the report.

Returns a success page on success, returns a new report on failure, showing 
the uncorrected entries.

    my ($class, $request) = @_;
    
    # Approve will also display the report in a blurred/opaqued out version,
    # with the controls removed/disabled, so that we know that it has in fact
    # been cleared. This will also provide for return-home links, auditing, 
    # etc.

        ## relies on foreknowledge in the template
        ## we basically tell the template, we can't approve, this uncorrected
        ## error is preventing us.

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

Requires report_id and entry_id.

Loads the selected entry id and all corrections associated with it. If there
aren't any corrections, it will display "no corrections found".
