 * This is to assit in calling function outside of the sps
 * module that might have side effect. It allows for test to
 * change the function for there tests
 * the syntax to use is
 *
 * sps_drupal()->FUNCTIONNAME(Param1, Param2, Param3);
 * eg.g sps_drupal()->drupal_get_form('sps_preview_form');
 *
 * if a param needs to be passed by reference the following syntax can be used
 * sps_drupal()->ref[FUNCTIONNAME](Param1, Param2, Param3);
 * eg.g sps_drupal()->set('drupal_get_form','sps_preview_form');
 *
 * if a test need to reset that function it can run
 * sps->call['drupal_get_form'] = 'test_drupal_get_form';
 * and then if something called drupal_get_form it would call
 * test_drupal_get_form instead.
