Description A server sends and receives data to and from its associated clients (other programs connected to it). When a server is started, it begins listening for connections on the port specified by the port parameter. Computers have many ports for transferring data and some are commonly used so be sure to not select one of these. For example, web servers usually use port 80 and POP mail uses port 110.
disconnect() Disconnect a particular client.
active() Return true if this server is still active.
available() Returns the next client in line with a new message.
stop() Disconnects all clients and stops the server.
write() Writes data to all connected clients
Server(parent, port)
Server(parent, port, host)
parent PApplet: typically use "this"
port int: port used to transfer data
host String: when multiple NICs are in use, the ip (or name) to bind from
