/**
* URIs are essentially structured names for things -- anything. This interface
* provides accessors to set and query the most basic components of an URI.
* Subclasses, including nsIURL, impose greater structure on the URI.
*
* 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
* \ / \ / \ / \ /\ /
* - --------------- ------ -------- -------
* | | | | |
* | | | | Path
* | | | Port
* | | Host /
* | UserPass /
* Scheme /
* \ /
* --------------------------------
* |
* PrePath
*
* The definition of the URI components has been extended to allow for
* internationalized domain names [2] and the more generic IRI structure [3].
