Cleaned everything up and refactored some more. The spearmint related stuff is now separated out into the scripts/ directory. Just running generate_spearmint.sh and passing the output directory location and the experiment json file to use will do all the work. Also got rid of the now redundant randomize_parameters method. Finally, made the agent_get_parameters method into a classmethod called agent_parameters (and made all the agents able to be run standalone in a way that uses the agent_parameters call to generate the argparser).
