*
* @brief Adds a weight if a constant resource of the specified type
* has the first event of a day later than the specified first period.
*
* This module is commonly used in school scheduling when it is desired that
* all teachers and/or all students start their day before or at a specified
* hour.
*
* For example, if you do not want students to have free periods in the
* morning:
*
* <module name="freemorning.so" weight="50" mandatory="yes">
* <option name="resourcetype">class</option>
* <option name="first-period">0</option>
* </module>
*
* @ingroup School scheduling, Multiweek scheduling
*/
/** @option resourcetype
*
* Use this option to specify one or more constant resource types. Specified
* resource types will have their timetables checked by this module.
*
*/
/** @option first-period
*
* Use this option to specify the first period. Resource types specified with
* the "resourcetype" option will have events scheduled so, that the first
* event each day will be at or before this period.
*
* If you don't specify this option, the default value of 0 is used.
