continuation of redistricting1 and CanvasGames project - using more modularization

1. Color Blobs 3 is a static web page that set up a grid with a selected number of randomly assigned cell colors.
2. load index.html to run. This will load a handful of pure JavaScript files
3. Current state can be saved (to downloads directory) or reloaded
4. The RUN/STOP will eventually generate new generations of the grid, with like-colors moving closer to each other.
5. an exercise in JavaScript and JS graphics

Observations:

1. This internally starts to resemble the MVC control pattern, with an interface/display layer above a state layer
2. Rediscovered that JSON utility does not completely capture the nested classes data structure, necessitating deserialization of the loaded state.
3. Canvas objects have a lot of properties, and height and width may 'not be the droids you are looking for'.

TODO:

1. Generation logic not defined (versions 1 and 2 were not satisfactory, and that led to refactoring this project)
