Display the details of a record on which some operation is to be carried
out and prompt for the user's confirmation that it is the correct record.
Upon the clicking of the confirmation button, augment step by one.
Given the "recid" (001) of a record, retrieve the basic metadata
(title, report-number(s) and author(s)) and display them in the
user's browser along with a prompt asking them to confirm that
it is indeed the record that they expected to see.
The function depends upon the presence of the "sysno" global and the
presence of the "step" field in the "form" parameter.
When the user clicks on the "confirm" button, step will be augmented by
1 and the form will be submitted.
@parameters: None.
@return: None.
@Exceptions raise: InvenioWebSubmitFunctionError if problems are
encountered;
InvenioWebSubmitFunctionStop in order to display the details of the
record and the confirmation message.
