/**
  * Saves all bundles on the specified screen in the database by extracting 
  * required data from the supplied request
  * $pm_screen can be a screen tag (eg. "Screen5") or a screen_id (eg. 5)
  *
  * Calls processBundlesBeforeBaseModelSave() method in subclass right before invoking insert() or update() on
  * the BaseModel, if the method is defined. Passes the following parameters to processBundlesBeforeBaseModelSave():
  *		array $pa_bundles An array of bundles to be saved
  *		string $ps_form_prefix The form prefix
  *		RequestHTTP $po_request The current request
  *		array $pa_options Optional array of parameters; expected to be the same as that passed to saveBundlesForScreen()
  *
  * The processBundlesBeforeBaseModelSave() is useful for those odd cases where you need to do some processing before the basic
  * database record defined by the model (eg. intrinsic fields and hierarchy coding) is inserted or updated. You usually don't need 
  * to use it.
  *
  * @param mixed $pm_screen
  * @param RequestHTTP $ps_request
  * @param array $pa_options Options are:
  *		dryRun = Go through the motions of saving but don't actually write information to the database
  *		batch = Process save in "batch" mode. Specifically this means honoring batch mode settings (add, replace, remove), skipping bundles that are not supported in batch mode and ignoring updates
  *		existingRepresentationMap = an array of representation_ids key'ed on file path. If set saveBundlesForScreen() use link the specified representation to the row it is saving rather than processing the uploaded file. saveBundlesForScreen() will build the map as it goes, adding newly uploaded files. If you want it to process a file in a batch situation where it should be processed the first time and linked subsequently then pass an empty array here. saveBundlesForScreen() will use the empty array to build the map.
