-/**********************************************************************
-* A class to represent a Uniform Resource Identifier (URI). This class
-* is designed to handle the parsing of URIs and provide access to
-* the various components (scheme, host, port, userinfo, path, query
-* string and fragment) that may constitute a URI.
-* <p>
-* Parsing of a URI specification is done according to the URI
-* syntax described in RFC 2396
-* <http://www.ietf.org/rfc/rfc2396.txt?number=2396>. Every URI consists
-* of a scheme, followed by a colon (':'), followed by a scheme-specific
-* part. For URIs that follow the "generic URI" syntax, the scheme-
-* specific part begins with two slashes ("//") and may be followed
-* by an authority segment (comprised of user information, host, and
-* port), path segment, query segment and fragment. Note that RFC 2396
-* no longer specifies the use of the parameters segment and excludes
-* the "user:password" syntax as part of the authority segment. If
-* "user:password" appears in a URI, the entire user/password string
-* is stored as userinfo.
-* <p>
-* For URIs that do not follow the "generic URI" syntax (e.g. mailto),
-* the entire scheme-specific part is treated as the "path" portion
-* of the URI.
-* <p>
-* Note that, unlike the java.net.URL class, this class does not provide
-* any built-in network access functionality nor does it provide any
-* scheme-specific functionality (for example, it does not know a
-* default port for a specific scheme). Rather, it only knows the
-* grammar and basic set of operations that can be applied to a URI.
