Detailed Description

Abstract interface to keep a registry of collection getter tools.

In order to represent associations by an index, we need to be able to get access to the collection within which we're indexing. We do this by optionally associating a label with a collection getter tool (this will typically be the object prefix). We can then look up the label here and make a copy of the matching getter tool. (We make a copy rather than using the original instance since the collection getters are stateful.)
