Title: _init() was not accessible because expected _init(self)

Found a minor bug with the Colormap abstract base class. If you try to instantiate it, self._init() should be called, and a NotImplementedError is raised. This does not happen because the definition of _init() was lacking the 'self' parameter.

Note: this my first attempt at a pull request and contribution, so any advice, suggestions are much appreciated.
