class Scale(Transform):
''' Base class for ``Scale`` models that represent an invertible
computation to be carried out on the client-side.
JavaScript implementations should implement the following methods:
.. code-block:: coffeescript
compute: (x) ->
# compute the transform of a single value
v_compute: (xs) ->
# compute the transform of an array of values
invert: (xprime) ->
# compute the inverse transform of a single value
v_invert: (xprimes) ->
# compute the inverse transform of an array of values
