When click the delete button, the status of related elements (e.g. for file, the elements includ file, related coding, related case category and file category) are set from 1 to 0. In this sense, deletion from GUI is temporary. After that, you can use list.deleted to show which ones are tagged as deleted. By pdelete, you can permenantly delete those tagged with temporarily deletion mark. By undelete, you can undo the temporary deletion, the status of related elements are set back to 1. When ask is FALSE, it will apply to all the propriate elements of specific type. When it is TRUE, you can choose the elements of the specific type which the action (pdelet or undelete) applies to.
