README.TXT - Server (Multi-thread) and client.

1. CLASSES
	1.1 SocketServer 		- Server
	1.2 SocketServerThread 	- Server threads, one for each client
	1.3 SocketClient		- Client for connecting to the server
	1.4 MathEngine			- Math logic of the program
	
2. STARTING
	To start the server run the main method of SocketServer,
	the server should try to start at the defined port. The
	port is defined in the source code of SocketServer.
	
	To connect to the server, run the main method of the 
	SocketClient. (port and host is defined in the source
	code of the client).
	
3. FUNCTIONS
	Once the client is connected you can ask the server to
	do calculations for you. Valid functions with examples:
	
	Standard functions		User-input			Server reply
	+						   5+5					10.000
	-					   	  10-8 					 2.000
	/						  10/3				     3.334
	*						   2*4					 8.000
	^						   2^4					16.000
