OP-118 AHRS: Added 6 point calibration routine to AHRS config widget. To use it, click "Cal Mode", then place the AHRS on each of 6 sides of a cube then click save position. Finally click compute to push the updated scale abd bias terms to the AHRS. Also fixed a bug in UAVObjectField that would not allow you to setDouble for extra fields.

AHRS: Added the filtered data to the attitude raw object. Even though this seems like an oxymoron it's still raw to the EKF algorithm, and nice to see the real values after filtering to make sure nothing weird is going on. However, if people don't like this I'm open to suggestions/patches. I'd maybe suggest the whole attituderaw object be converted to ahrsraw anyway since it's more like that (eg. none of the values are actually attitude estimates).

AHRS: Fixed another bug in decimation code - I stupidly used Matlab 1 based indexing. Adjusted timing of AHRS so it can process all the data and doesn't miss updates. Finally adjust all inputs to INS to have correct sign and orientation (I think). This is X is forward, Y is right, and Z is down which is mentioned in the forum as our standard and fits the algorithm. The magnetic sensor driver should be modified to return in this order (currently reads X,Y,Z registers which maps to left, back, up) but maybe since it's a board dependent orientation it's better where it is.

[PIOS] The ADC mappings are strange because of the way the DMA engine works. Basically data is packed 16 bits ADC2 then 16 bits ADC1 channels, so the accels are pins [4 2 0] currently. Also there is inconsistency between the names of the pins in the config file which uses 1 based indexing and the index for PIOS_ADC_PinGet which is zero based and has to account for this interleaving. Probably should adjust config file to be zero based and then to make those pin numbers map to the function call. The actual order they appear is arbitrary as the ADC engine can scan in whatever order.

a basic level, capable of moving simple single byte messages between
