Documentation of matching and merging - names & IDs

[drserajames]

mergeMaps(maps), match_mapAntigens(map1, map2) and match_mapSera(map1, map2) seem to match on IDs if present, and Names if not. mergeMaps(maps) documentation doesn't describe how the ag & sr are matched. match_mapAntigens(map1, map2) describes matching by name.

Another way to do this would be an additional attribute:agMergeIDs(map) and srMergeIDs(map). These would take the value of IDs if present and Names if not. But could also be set by the user, without over-writing the information in IDs. Or perhaps that's how you see the current IDs. And perhaps I need a srLabIDs(map) to keep the IDs.
