   *
   *  - Removed psuedo-scheduler, dynamic memory block allocator from the library (no longer needed and not used respectively)
   *  - Added new class drivers and matching demos to the library for rapid application development
+  *  - Added incomplete device and host mode demos for later enhancement
+  *  - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed
