Simple Mining Productivity spreadsheet

[Honktown]

I made a personal spreadsheet for infinite Mining Productivity research for 0.16.51 which can be used to calculate the break-even point of infinite resources with and without productivity modules. Was wondering if anyone would like it, and I could update it for .17 costs and the change to Mining Productivity. Also to expand it to include stone (before it was left out, since it wasn't used much). It covers raw ingredient costs, and passes values through the chain of production to determine the cost per-unit of an item and science packs.

Attached is a screenshot of the "results".
