	Dependencies : TUriComponent.

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.
