/**************************************
This is the main file for the "RyanEXO" control software.
This sets up the main control loop that operates at a 1kHz frequency
and controls the flow of the rest of the software

The configuration for the exo system that this software runs:
amplifiers: 2 Copley Controls 10A digital amplifiers
sensors: 2 Austria Microsystems 12 bit magnetic encoders, handled by encoders.h
motors: 2 maxon EC90 DC brushless motors, handled by HipMotorControl.h (called in FSM.h)
Knees: wrap spring clutch controlled by Firgelli PQ12P linear actuators, controlled in linearActuatorControl.h
