	Dependencies : TUriComponent.

	Comments : Provides non-modifying functionality on the components of a uri object as

	defined in RFC2396. There are 5 components; scheme, authority, path, query and fragment.

The	object holds descriptor pointers to the parsed uri components and a descriptor pointer 

to the uri. It is non-owning. It uses 16-bit descriptors.

	The functionality provided by this API allows the uri components to be extracted from the 

	parsed uri, checked for their presence in the uri and be compared with those in another 

	TUriC16 object.

Dependencies : TUriC16

Comments : Provides functionality to parse a descriptor into the components of a uri as 

defined in RFC2396. There are 5 components; scheme, authority, path, query and fragment.

It uses 16-bit descriptors.

Format of a uri is; scheme://authority path?query\#fragment

@warning The descriptor that is parsed by an object of this class will be referenced 

by that object. If the original descriptor is no longer in scope there will be undefined 

behaviour.
