          Arguments
          ---------
          point : list/tuple
              point to which the transform will be applied
  
          Returns
          -------
          list : transformed point
  
          Example
          -------
          >>> import ants
          >>> tx = ants.new_ants_transform()
          >>> params = tx.parameters
          >>> tx.set_parameters(params*2)
          >>> pt2 = tx.apply_to_point((1,2,3)) # should be (2,4,6)
