Be more clear with the default options documentation

[mrandri19]

In the documentation for the default settings it is not clear that it will serve files from the ./public directory.

//1. serve with default settings
var server = gls.static(); //equals to gls.static('public', 3000);
server.start();

Just add //This will serve the files from the ./public directory

Also as of now i couldn't serve my files from ./public until i explicitly wrote gls.static('public', 3000);
