Attribution is provided for groups of files that share a common prefix.
Each group can have one or more authors. Each file has one source.
This information is displayed when an entity is selected.

Includes a demo scene, some of the military-themed macros, and then selections
of entities of varying sizes

Mostly just avoiding things like the position of the entity holder over and over.
I should probably switch it so that it just reads, then writes. TODO!

Each entity now has an info object, a views list, and a sizes list.
This will allow for more complex bio/description text
