Solving for skeinforge flow rate

Volumetric 5D may make this obsolete.. Also, the "work in progress" note from Thingiverse is no joke! It's very much a work in progress. In particular, it's better at lower thread widths than higher ones - you'll probably need to add a bit to the flow rate as widths get higher.

Just a simple program that I was goofing with to find the correct flow rate of a skeinforge profile given some other set of parameters. Most params have min, max and increment values. The program is simply a set of nested loops that iterate through these values - from min to max, adding the increment each time.

Since this solves for a range of flow rates, you may have problems if you give it too narrow of a range for flow rates. If you're looking for a very specific flow rate, use values like "1.9" min and "2.1" max instead of setting both to "2.0".

Mostly obvious stuff if you've messed with skeinforge before except:
- Gear diameter: this is the diameter of your filament drive gear. Preset to the defa
