Fixed Bend Sensor Calibration

Tom and I implemented the checksum processing on Glover and found that this prevent the bend sensor calibration from failing.  Without the checksum, parts of longer packets were being incorrectly interpreted as short bend sensor packets and resulting in extreme values being processed as measurements.

We also did a quick test to see how well the Glover’s Neural Network classified different postures with only 4 bend sensors in the Right glove.  It performed surprisingly well and only struggled to distinguished between a ‘puppet hand’ pose and ‘fist’.  We expected this but think it could be solved if the bend sensors were to measure the entire length of the finger rather than just the knuckle.
