/**
 	 * @internal The following functions each print out filter field inputs.

 *
 * 		print_filter_[filter_name]
 *
 *      Where [filter_name] is the same as the "name" of the form element for
 *      that filter. This naming convention is depended upon by the controller
 *      at the end of the script.
 *
 * @todo print functions should be abstracted.  Many of these functions
 *      are virtually identical except for the property name.
 *      Perhaps this code could be made simpler by refactoring into a
 *      class so as to avoid all those calls to global(which are pretty ugly)
 *      These functions could also be shared by view_filters_page.php
