Flight/AHRS: Reorganized the code a little to make sure indoor used by default unless GPS updates come

in. Also change the velocity variance in indoor mode to lower to make it get a better attitude estimate (primarily faster convergence - probably will tweak this in the future dynamically). Finally decreased barometer variance - in scope it's actually quite reasonable, normally within +/- .5 m.

OP-132 AHRS: Changes to the Indoor flight handling to only use the barometer indoors and update with a zero for velocity and high variance.

OP-132 Flight/AHRS: Changed the heuristics regarding GPS quality and INSGPS updates. Now if satellites < 7 or PDOP > 3.5 it does not perform GPS updates. Professor is working on some code to fix parts of the covariance matrix. If indoor updates high a 0 position and velocity and high variance.

OP-132 AHRS: Added an indoor flight mode and also add an ad-hoc quality heuristic to the GPS signal to increase the measurement variance from GPS when fix quality is poor or when in indoor flight mode. In addition corrected the indentation to conform to the tab/space convention forum discussion.

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.

AHRS: Fixed bug in the downsampling code (used a += a + blah, dumb). Also added initialization of the magnetic flux based on fixed GPS settings (I hope you're near Houston). I will add the GPS communication shortly.

Behaving reasonably, added calibration code which runs by default on startup and take 6 seconds - this will be called from GCS in future and saved to SD card.

Added a testing function for INS - currently doesn't stabilize for fixed inputs. Fixed two bugs I found in INSGPS (R[10] instead of R[9] initialized and Nav.Pos[2] was set to wrong X element).

Adding the code from Dr. Dale to the AHRS. Currently diverges though, but not on the PC.
