   ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points.
      [R, T] = icp(model,data)
      INPUT:   
      model - matrix with model points, 
      data - matrix with data points,
      OUTPUT:
      R - rotation matrix and 
      T - translation vector accordingly 
          so
          newdata = R*data + T .
   newdata are transformed data points to fit model
