Implements Weighted Improved Gregory Single Transferable Vote based on Scotland's rules.
Run and log the Election.
The Scottish Rules specify 5 decimal places, a weight of 100,000 is used which is equivalent.
When more than one choice is Pending the rules call for a full Stage to elect each of them. Pending Choices cannot recieve additional votes, this implementation elects, charges, and rebates the Pending Choices, then starts a new Round. The final result will be the same, but Vote::Count::Method::WIGM rounds will not always match the stages.
Small discrepencies with the stages data available for testing have been seen, which are likely to be rounding issues. Until further review can be taken, this code should be considered a preview.
