// Plug-in 69: Manage Cookie
//
// This plug-in provides three ways of interacting with
// cookies. It must be called before any HTML is sent.
// Upon success with a 'set' or 'delete' the plug-in returns
// TRUE. For a successful 'read' it returns the read value.
// On failure it returns FALSE. It requires the following
// arguments:
//
// $action: If 'set' then set $cookie to $value
// If 'read' return the value of $cookie
// If 'delete' delete $cookie
// $cookie: Name of a cookie to set/read/delete
// $value: If setting a cookie use this value: any string
// $expire: If setting a cookie use this value: number
// of seconds before cookie expires, or use
// NULL to let cookie expire at browser session
// end
// $path: The path to the cookie on the server:
// Generally this will be '/'
