========== TODO: ===========
- Fix bootloaders - make compatible with smaller USB AVRS (USB_IsConnected, RAMPZ)
- Fix bootloaders - make compatible with smaller USB AVRS (USB_IsConnected)
- Document new device class drivers
- Made new host class drivers
- Document new host class drivers
- Convert Host mode demos to class drivers
- Convert Host mode demos to schedulerless
- Add standardized descriptor names to class driver structures, controlled by USE_NONSTANDARD_DESCRIPTOR_NAMES
- Device demos error if endpoint config fail

*
* - 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
