WIP… reading fractal configuration from YAML in Haskell version.
Cleanup tests for Haskell processing of YAML options.
Delete the old Options module.
Rename `SetMembership` to `FractalMembership`; move PPM to Fractals.Color;
create `ColorMap`; use `ColorMap` in `Options`.
Remove Coord.hs since it was a sandbox.
Move Options2 module to Fractals.Options.
Improve CLOBBER file list in Haskell's Rakefile.
Refactor tests.
Parse color maps for Options in Haskell.
Get rid of some commented-out old code.
Get main Haskell driver compiling again after improving Option parsing.
Change Haskell Rakefile to compile everything before running tests.
Add "gray" as a recognized color scheme in Haskell code.
Update YAML file to new format.
Fix the Haskell driver.

THE GODDAMN THING WORKS!
Add 'parallel' task back to Haskell.
