 	Match returns ETrue if aMatchType is found within aImplementationType according to

 	bars (||). ETrue is returned if aMatchType matches exactly any of the short 

 	descriptors.  If no double bar is present then aImplementationType is treated as a

 	single descriptor.

 	2) If aUseWildcards == ETrue then a '?' in aMatchType will be matched to any single

 	character and '*' will be matched to any series of characters.
