server 

	RemoteCommandServer is a top level object that doesnt do much.
	TCPServer is a subclass of SocketServer.ThreadingTCPServer
	TCPServer doesnt do much either. MessagingHandler is where the real work
	happens. 
	
	The TCPServer listens for incoming commands and creates a new MessageHandler object for each 
	request ie command and calls its handle function
	
	The handler object gets the data from the socket, processes it, and returns the result
	
	To process requests the command is repeated using the CommandRepeater to the CommandProcessor
	living in Pychron
	
	The CommandRepeater prepends a process_type string to the beginning of the request so the
	RemoteHardwareManager knows how to handle the request. The process_type and data are 
	separated by a pipe character ex. 'System|Open V'
	
	CommandProcessor is a simple socket server, (NOTE: isnt a subclass of a SocketServer, uses a 
	listener thread to wait for requests from CommandRepeater)
	
	When CommandProcessor receives a request its passed to
	RemoteHardwareManager.process_server_request
