config.default.yaml should be copied to config.yaml by new users.
That way config.yaml doesn't change every time the developers use new
settings.
A basic "Getting Started" section is added to the README.
Changes to be committed:
modified: .gitignore
modified: README.md
renamed: config.yaml -> config.default.yaml
These are different for residential and services demand.
Also include Snakefile in config files copied for each run.
Use gurobi settings from gurobi support for speed.
Commented out settings for testing randomness for noise.
