/* Lists a user's reports or displays a specific report.
 *
 * Input Parameters:
 * - <var>report_id</var> (optional) - specified report id in webcal_report table
 * - <var>offset</var> (optional) - specifies how many days/weeks/months +/- to
 *   display. For example, if the report type is 1 (today) with offset=5, then
 *   the report will display 5 days from now. Should only be specified if
 *   report_id is specified. Will be ignored if specified report does not have
 *   the webcal_report.cal_allow_nav field set to 'Y'.
 * - <var>user</var> (optional) - specifies which user's calendar to use for
 *   the report. This will be ignored if the chosen report is tied to a
 *   specific user.
