Log:
- Access to information about courses in a domain with six character
unique codes (html, xml or csv format).
- Initial use case is for a separate portal (token-based auth)
where students enter the code to sign up for a specific "textbook"
course.

=head1 NAME
listcodes.pl
=head1 SYNOPSIS
CGI script to display course codes and associated
information as plain text or XML.
Possible formats are: plain text (CSV), XML or HTML
and the desired format is specified in query string.
The query string should also contain the domain for
which this data is being requested.
The current server needs to be the homeserver of the
special domconfig "user", which will be the primary
library server in the domain.

=pod
=item show_results()
Inputs: $reqdom - domain for which unique codes and course information
are to be shown.
$format - format for output, one of: html, xml or csv. csv
is the default, if no format specified.
$getshash - references to hash of key=value pairs from the
query string. Keys which will be used are: code,
and num.
Returns: $count - number of items detected
$output - output to display.
If there are no matches, or the input argument
(code or num) was invalid, no output is returned
unless the requested format is html.
Note: in the case of a query without a
specific code or courseID, the output
is printed within the &show_results()
routine when looping over courses retrieved
by a call to lonnet::courseiddump, so $output
is blank, in this case, unless no courses match.
Description: Displays LON-CAPA courseID, unique codes, course owner,
and course title.
Data displayed can be a single record, if the query string
contains code=<six character code> or
num=<LON CAPA course ID>.
Data formats are: html, xml, or plain text (csv).
