// Reading a Cookie
bobCookie.read();
// Killing a Cookie
bobCookie.kill();
// This changes the inner name of the cookie,

/****************************
SIMPLE FUNCTIONS

/*****************************
SETTING A COOKIE
Parameters are:
Name, Value, Expire in days, Path, Domain, Secure
Only Name and Value are required.  Others are optional.
*****************************/
//new cookie('myCookie', 'Yessir!', 7, '/').set();


/*****************************
READING A COOKIE
The only parameter is Name
*****************************/
//new cookie('myCookie').read();


/*****************************
KILLING A COOKIE
Name is required.  Path, and Domain are only required 
if they were used in setting the cookie.
*****************************/
//new cookie('myCookie', '/').kill();
