classmethod section makes sense ...

[dalehenrich]

In the context of the evolution of a script ... it starts with just a few simple extension methods, but as the script becomes more complicated, it reaches a point, where a class side api is called for and the script instance side methods and doit section should be refactored in expectation of the split into a first class class with a full api callable from the script, in the image or other scripts ... which implies support for creating a Rowan project or merging the class into a utility project that has a collection of small projects that can be used as components of other scrtipts ... maybe create a superDoit-utilities project for housing these puppies ...
