-The original motivation for this file is name collision. It's possible
-to have two of the same gene, user defined and diffexpressed, on the client
-simultaneously, looking at the same data in the cache but with two
-dimensions and two crossfilters. It's also possible that someone could
-have a obsAnnotation named X, but we are using that for layout. So
-we namespace, and abstract to avoid proliferating strings throughout the
-codebase.
-
-It is _no longer_ used to remove collisions in the crossfilter or
-anno matrix namespaces. It is still used by the component tier.
