/**
* formslib.php - library of classes for creating forms in Moodle, based on PEAR QuickForms.
*
* To use formslib then you will want to create a new file purpose_form.php eg. edit_form.php
* and you want to name your class something like {modulename}_{purpose}_form. Your class will
* extend moodleform overriding abstract classes definition and optionally defintion_after_data
* and validation.
*
* See examples of use of this library in course/edit.php and course/edit_form.php
*
* A few notes :
* form defintion is used for both printing of form and processing and should be the same
* for both or you may lose some submitted data which won't be let through.
* you should be using setType for every form element except select, radio or checkbox
* elements, these elements clean themselves.
*
