Initial Release

This is the first release. Goodies in this release:

• shared interface for parallel julia jobs and slurm job arrays. Shared interface lets you test in one and use in the other (or should, this needs to be tested a bit more).
• parse_args and custom_parse_args: An extension to the ArgParse package which automatically determines the save file based on a hash or custom function and the current arguments. Keeps directories flat.
• ArgIterator: Great tool for iterating through a cross product of arguments. Good for experimental sweeps.
