Added design files for rev 2 of strain gauge digitizer board.
Calibrated hip encoders.
Created script for rtnet module control`
Merge branch 'master' of https://code.google.com/p/atrias
New parameters and a fix for atc_canonical_walking
Fixed the bug of angles of leg A and B being the same.
Also Fixed a few other bugs. (computing 'tau' and 'dtau')
Updated the theta_limits to the current correct value.
Fix calibration values and add script to build all controllers
Added safety to RT Ops to detect NaN and other nonfinite current commands.
Added 2 more safeties to the canonical walking controller.
Adding rate limit safety to hips
Putting in a rate limit on manual tau control in atc_canonical_walking

Also, I changed the default tau value to prevent jumps when switching from Stand to Walk.
Merge branch 'master' of https://code.google.com/p/atrias
Fixing ATCJointPosition name.
Changed the initial condition to joint angles.
Changed the walking parameters. Minumum knee angles about 0.62 rad.
Added debug statement and to canonical walking.
Calibrating boom Z encoder
Adding a facility to let us calibrate the pitch encoder.
Swapped left/right leg. Turned off D controller.
Temporary (until the body is unlocked) calibration on the pitch encoder done.
