[Major Update] Impartial Leader Selector

[Shad]

various demands

Hi Vince,

Robin's been working hard on loading leader OOBs, but the tool's design and maintenance falls squarely on my shoulders.

I wasn't planning on doing much site work during December, but wanted to knock out the basic version of the tool before then and see how it was received.

For stand-alone scenarios that require double-counter sets and for all expansions, you will need to wait patiently. I plan to implement them in due course but probably not until January. I need a break too.
