+/* Proove
+ *
+ * 
+ * Tested devices:
+ * Magnetic door & window sensor
+ *
+ * From http://elektronikforumet.com/wiki/index.php/RF_Protokoll_-_Proove_self_learning
+ * Proove packet structure (32 bits):  
+ * HHHH HHHH HHHH HHHH HHHH HHHH HHGO CCEE  
+ * H = The first 26 bits are transmitter unique codes, and it is this code that the reciever “learns” to recognize.  
+ * G = Group code. Set to 0 for on, 1 for off.  
+ * O = On/Off bit. Set to 0 for on, 1 for off.  
+ * C = Channel bits.  
+ * E = Unit bits. Device to be turned on or off. Unit #1 = 00, #2 = 01, #3 = 10.
+ * Physical layer.
+ * Every bit in the packets structure is sent as two physical bits.
+ * Where the second bit is the inverse of the first, i.e. 0 -> 01 and 1 -> 10.
+ * Example: 10101110 is sent as 1001100110101001
+ * The sent packet length is thus 64 bits.
+ * A message is made up by a Sync bit followed by the Packet bits and ended by a Pause bit.
+ * Every message is repeated four times.
