Desc: Defines the UE9 class, which makes working with a UE9 much easier. All of
      the low-level functions for the UE9 are implemented as functions of the
      UE9 class. There are also a handful additional functions which improve
      upon the interface provided by the low-level functions.

To learn about the low-level functions, please see Section 5.2 of the UE9 User's Guide:
