class PresentationDeleteForm in Isotope (with Masonry and Packery) 8

Class PresentationDeleteForm.

Provides a confirm form for deleting the entity. This is different from the add and edit forms as it does not inherit from PresentationFormBase. The reason for this is that we do not need to build the same form. Instead, we present the user with a simple yes/no question. For this reason, we derive from EntityConfirmFormBase instead.
