Fixed a lot of the commenting and layout of the code in the AVR project.  Added the functionality to program the masterlevel and the mode.  Added a sort of state machine style mode to the AVR where it can either be in content, peak, or data mode.  Since the baud rate won't allow the content mode to work they needed to be separated.  This means that the device will either turn on lights based on the content in a specified band, based on a peak in a band (not yet implemented), or just ignore the lights and send the data out to serial.  Unfortunately this will still be lossy as the slow baud rate wont allow for all of the data points to be transferred by the time the DMA buffer fills up.  (42ksps is too fast for 115200 baud rate)
