 * Page Description:
 * This page will present the user with forms for submitting a data file to import.
 *
 * Input Parameters:
 * None
 *
 * Comments:
 * Might be nice to allow user to set the category for all imported events.
 * So, a user could easily export events from the work calendar and import them
 * into WebCalendar with a category "work".
