Closes #72 - updates alias list to maintain a map of alias id to alias and separate lists for wildcard alias id values. Alias lookup logic is changed to first look for in the alias map for a concrete match to the alias identifier. If an alias is not found, then the list of wildcard alias identifier values is iterated looking for a matching wildcard. If the wildcard is found, then the matching alias is returned from the map.
