Create USRP Driver

[jimblanc]

We need to create a HWM driver that can interact with the USRP B100 via Srinagesh's custom GNU Radio script. The driver must allow the radio to be configured, relay the radio data socket, and use a 'tracker' pipeline service to provide doppler updates to the radio. In addition, the driver will need to provide waterfall and FFT information via the device's standard telemetry stream.

This has been completed and a full suite of unit tests has been written. However, the driver still needs to be tested in a deployment environment which I plan on setting up within the next few days.
