 Galois field arrays also have constructor class methods for convenience. They include:

 Galois field elements can either be displayed using their integer representation, polynomial representation, or
-power representation. Calling `FieldClass.display` will change the element representation. If called as a context

 manager, the display mode will only be temporarily changed.
