with the Kajita's dynamic filter

Adding oder 7 polynome to be used to compute X,Y,Theta position for the feet.
Do a little cleanup of the computation of the foot position.

Creation of function that compute the position of a third step to interpolate elong the whole preview contrl, still debugging.

the modification bring contunous CoM and ZMP along time but increase the error between the zmp ref and the zmp multibody

replacement of the RigidBodySystem class by the OnLineFootTrajectoryGeneration to compute the interpolation of the feet trajectory
