Description

Currently it enumerates all objects recursively until an object matches. In #2712 @bjorn pointed out that this is kinda silly for an ID field. We should add a map<ID, object*> of some kind.

Research direction

Start by locating Map::findObjectById and reviewing how it recursively enumerates objects and how object IDs are managed. Determine where a map from IDs to objects can be maintained; done means findObjectById uses that lookup and still returns the matching object correctly.
