docstr: Sets the static image being compared against the moving one.
  
  Sets the static image. The default behavior (of this abstract class) is
  simply to assign the reference to an attribute, but
  generalizations of the metric may need to perform other operations
  
  Parameters
  ----------
  static_image : array, shape (R, C) or (S, R, C)
      the static image
