WiFi : Client class
Connect to the IP address and port specified in the constructor. The return value indicates success or failure. connect() also supports DNS lookups when using a domain name (ex:google.com).
client.connect(ip, port)
client.connect(URL, port)
ip: the IP address that the client will connect to (array of 4 bytes)
URL: the domain name the client will connect to (string, ex.:"arduino.cc")
port: the port that the client will connect to (int)
Returns true if the connection succeeds, false if not.
