Function for reconstruction of a measured motion.

KEDATA = KINEMATICS_TOOL_reconstruct_motion(KEDATAin, SSDATA, BLDATA, REDATA)

File Description:
Having filtered, transformed, and estimated the landmarks
this function takes the measured kinematics data from SSDATA and
reconstruct this motion using inverse kinematics. More precisely, it uses
global optimization technique to define the generalized coordinates for
each time step of the measured motion such that the tracking error is
globally (for all the landmarks at each time step) is minimized. It also
takes into account the constraints on the scapulothoracic joint using
KINEMATIC_TOOL_nonlinear_constraints.
