simpleStatic is a simple and easy to configure http static server.

give simpleStatic a path to a configuration file like so:
	simpleStatic /home/wesley/.config/simpleStatic.conf

a configuration file is lines of key/value pairs delimited by a ':'
the defaults are like this:
	port:8888
	static_directory:./static
	log_file_path:
	# NOTE: if the log file path is empty it will default to stdin
	# Also, that there are no spaces between the key and the value
		`
