* Look at limiting batting/throw power with math.log()
* Extract draw/fielder.lua
* Extract some values into constants.lua
* Extract npc.lua for computer batting (and eventually probably more CPU behavior)
* pitchTracker in utils
Put utils functions into a module. Of sorts, anyway.
Add benchAllFielders()
Add playerIsOn() and associated "sides".
Pass appliedSpeed through into runner funcs. Should make it easier to put under NPC control.
Use PascalCase for all constants, explain in new README.
Split 'make check' into a separate command (less likely to shift your files out from under you than 'make lint')
Add __stub.ext.lua with quick explainer for why it's useful.
