/**
 * Implements hook_civicrm_buildForm() is a completely overkill way.
 * Searches for an override class named after the initial $formName
 * and calls its buildForm().
 *
 * Ex: for a $formName "CRM_Case_Form_CaseView", it will:
 * - try to find * CRM/Symbiotic/Case/Form/CaseView.php,
 * - require_once the file, instanciate an object, and
 * - call its buildForm() function.
 *
 * Why so overkill? My buildForm() implementations tend to become
 * really big and numerous, and even if I split up into multiple
 * functions, it still makes a really long php file.
