		* and pattern. Matching expressions support the following wildcards:
		*
		* 1) An asterisk (*) matches zero to as many characters as possible
		* 2) A question mark (?) matches any single character.
		*
		* Matching one to many characters can be done with a question mark followed by an asterisk (?+).
		*
		* @param expression A matching expression string from a DAL relation extension component used for
		* matching a URI part. This must be a non-empty string and all characters in the
		* string should be decoded.

		* @return Returns a Pair containing a {@link android.os.PatternMatcher} type and pattern.
