This class permits manipulation of URLs and the
resources to which they refer. They can be used to
represent absolute URLs or relative URLs which are
based upon an absolute URL. The relevant RFCs
describing how a URL is formatted, and what is
legal in a URL are - 1808, 1738, and 2396. <br />
Handling of the underlying resources is carried out
by NSURLHandle objects, but NSURL provides a simplified
API wrapping these objects.
