DME Starter Calculator Tool

Title basically says it. I don't want to create an entire recipe for a DME starter, but I'd prefer to use BS to an online calculator to give me what I need.

Basically a calculator where you enter two of three variables, and BS calculates the third. The three variables being:

- Desired Gravity
- Volume of water to use
- (Grams|Ounces|Etc.) of DME to use

Additionally, this could be added to the "Starter" tab of recipes for "Suggested starter size, suggested DME/water quantities"

Be neat if it went by pitch count and yeast inventory.

Like:

a recipe your making calls for 250 billion cells...
You select 50ml frozen flask of wyeast 1056 slurry for the recipe from inventory, which is dated 6 months ago.
your starter equipment profile knows what flasks you have, and whether or not you use a stir plate, and recommends which flasks, how much water and dme to get your pitch count in a few as steps as possible.
