 * URIs are essentially structured names for things -- anything. This interface

 * This interface follows Tim Berners-Lee's URI spec (RFC2396) [1], where the
 * basic URI components are defined as such:
 *  
 *      ftp://username:password@hostname:portnumber/pathname
 *      \ /   \               / \      / \        /\       /
