start()-> {ok,Pid}| {stop,Reason}

Start WebTool with default, port 8888, ip-number 127.0.0.1, and server-name localhost. The configuration data is assumed to be in the directory webtool-vsn/priv.

start(Path,Data)->{ok,Pid}|{stop,Reason}

Use this function to start WebTool if the default port, ip-number,servername or path to the configuration data not can be used.

If Data is set to PortNumber, the ip-number and server- name will be retreived by calling inet:gethostname/0 and inet:getaddr/2.
