Clean out unused test scenes
Clean up formatting and add comments

Properly use require chain to define dependencies for each component rather than loading them all from the

explanatory comments to Container component.
Add explanatory comments to migrator component
Processor node first draft

New test scene for processor node works correctly with collector moving from resource to processor and
processor toggling busy for time set as processorDelay.
Improve extensibility of processor and collector

Processors still don't do anything with their processed material, but
the exchange.completed handler is split into startProcessing and
finishProcessing methods.

Collectors may now be configured with Crafty selectors specifying their
source and destination entity types.
Create commented module files
Create first drafts of storage and exchange modules

No testing yet, still in flux. Exchange is an incomplete draft.

drive module, both powered by a battery storage module.
