Progress on Framework for Server software

We have:
 - Threaded stuff for sensors that stores data in a buffer and periodically dumps it to a binary file
   - The use of the buffer reduces the number of times the mutex must be acquired (mutex = expensive)
   - Will do some tests to see if the buffer improves performance
 - Dummy function for querying sensors
 - Sensor Handler function (QuerySensor) gets data from binary file, dumps to a buffer and then prints

There is something not quite right; QuerySensor appears to get the most recent dump that the sensor thread made.
eg: In the current version, dumps are made twice as often as queries, so you miss half the data.

Should be able to fix this after more sleep...
