 *  \section SSec_Description Project Description: 
 *
 * This bootloader enumerates to the host as a HID Class device, allowing for Teensy compatible programming
 * software to load firmware onto the AVR, such as the official software at <a>http://www.pjrc.com/teensy/</a>.
 *  
 * Out of the box this bootloader builds for the ATMEGA32U4, and will fit into 4KB of bootloader space. For other
 * devices, the makefile will need to be updated to reflect the altered MCU model and bootloader start address. When
 * calculating the bootloader start address, use (TARGET_FLASH_SIZE_BYTES - 4096).
 *
 * This spoofs (with permission) the official Teensy bootloader's VID and PID, so that the software remains
 * compatible with no changes.
 *
 *  \section SSec_Options Project Options
