	Class: OptionsManager

	The OptionsManager is responsible for managing the global options available in the
	client. When the client is run the command arguments are parsed and sent to this
	object so that they are globally available to all other objects in the system. It
	is a singleton so only one object can exist and provides an easy centralised place
	to manage options. In the future when the standalone version is worked on more this
	will allow a config file to be saved to a disk easily so that options can be persistant
	and changed at any time
