/**
 * This file defines the main teambuilder configuration form
 * It uses the standard core Moodle (>1.8) formslib. For
 * more info about them, please visit:
 *
 * http://docs.moodle.org/en/Development:lib/formslib.php
 *
 * The form must provide support for, at least these fields:
 *   - name: text element of 64cc max
 *
 * Also, it's usual to use these fields:
 *   - intro: one htmlarea element to describe the activity
 *            (will be showed in the list of activities of
 *             teambuilder type (index.php) and in the header
 *             of the teambuilder main page (view.php).
 *   - introformat: The format used to write the contents
 *             of the intro field. It automatically defaults
 *             to HTML when the htmleditor is used and can be
 *             manually selected if the htmleditor is not used
 *             (standard formats are: MOODLE, HTML, PLAIN, MARKDOWN)
 *             See lib/weblib.php Constants and the format_text()
 *             function for more info
