SensorAlgorithm beta completed for detecting car ins and outs

This is a c++ algorithm for detecting cars using the HMC magnetometer
sensor data taken 5.10.13
The script is <will be> designed to re-calibrate the 'baseline' being
used as the baseline values every 10 minutes.
There is also a moving average aglorithm to smooth out noise. Currently
this only uses the X axis data (as that may be all we need)
Using datasets taken at the CTLM exits and entrances, it correctly
calculates entrances and exits.
