Calibration: In each of the 6 positions store the average gyro value as well
the influence of linear acceleration on the gyros.

For now just output the results to the command line.
Cross axis calculation: Require 500 samples to measure this well
Calibration: Code to collect the data for temperature calibration of the
gyros.  Calculation is not implemented yet.
Calibration: First pass of the calculation code
Simulation: Add temperature influence
GCS Temperature Calibration: Add visualization of the data and fitted curves
Gyro temp compensation: Use this on the firmware side
GCS Temp calibration: When computing level account for any existing temp
cal instead of overwriting it.
Calibration: Update the display periodically
GCS Calibration: Add a cancel button
Use the same configuration gadget for CC and Revo
Temperature Calibration: Get the temperature calibration working on CC3D.
Need to cover CC case which has no temperature measurements.
Fix compilation errors
GCS Temp cal: Fix UI so it works for CopterControl or Freedom
GCS Temp Cal: Add accept button which will take the results of calibration early
GCS Temp Cal: Show the calibration coefficients
Calibration: Add a flag which indicates whether to use the whole hardware
Calibration: Add back the accel and gyro ranges
Fix some capitalization for case sensitive operating systems :)
Attitude UI: Remove the accel and gyro range selectors

These are board specific hardware settings and no longer
below on the general attitude page.  These should be on
the hardware configuration page.
