Added threading to the UI program.  This thread will be started with the connection with the AVR is established, and will continuously attempt to pull points from the AVR and graph them on the UI graphs.  The thread will automatically be closed when either the program closes or the graphing is stopped.  It may be necessary to have a way to let the user select a mode due to the nature that by transferring serial data the timing of the FFT and light selection on the AVR is disrupted.  If both operations cannot be completed simultaneously then the device will need to be in either one mode or the other.
