Added Doxygen documentation to the Audio class driver. Added new modules for each of the new device class drivers to the library documentation.

Ensure all USB device class drivers have the same three main functions as their interface for consistency.

Redocumented all device demos, now that they have changed over to the new USB class drivers.

Added C linkage to class drivers for C++ support.

Added prefixes to most of the class driver constants to prevent name clashes.

Removed new Start of Frame event from the library; performance suffered far too much and it was only useful in one of the standard classes (HID). Altered HID demos to use the previous method of tracking millisecond periods via a hardware timer rather than the SOF events.

Fixed MIDI class driver blocking on unread events to the host.

Add MIDI class driver, update MIDI device demo to use the new USB class driver. All device demos/projects have now been converted to the new library class drivers, although documentation is yet to be completed.

Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet.

Removed scheduler and memory allocation libraries.

Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).

Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.
