Added a test file for a TX/RX mod
ditched the commented out code
Added a simple transmit to the Pi Side and started work on a reciever.

The Reciever code will be added to the Energy Monitor so I can have a LCD
Display near the front door with messages and such like.
Got the pi transmitting to the Test Rig. Need to clean up the test rig
Done some tests and improved the data handling on the RX for the LCD.
put data into the buffer via i2c on the pi, tx with 0xff 0xfb

using i2cset data can be put into the tx buffer, once data is buffered it
can be transmitted with 0xfb at address 0xff, once the data has been
transmitted the buffer can be cleared with 0xfd at address 0xff.

I need to check the incoming data on the RX side (Maybe add CRC-8 or
something) and if the data check fails tell the TXer to try again, once
the data checks out send a OK command which will wipe the buffer.
