Changed pelvis 6-state initialization to match first-time-step solution
(values are slightly different from given init states,
unstable controller, since controlCOM is active and not consistant with pelvis)
First version with resolved initialization for standing with pelvisZeroAcc
(initialized states all to zero, inactivated controlCOM,
stable standing for 70 time-steps)
Added three osimModels used for this simulation to git
(springactive_noload_static_trial_subject01,
normal, with muscle, with contact)
