MediaWiki approval voting code

MediaWiki currently lacks approval voting code with general applicability. It does have approval voting code specifically designed for the Wikimedia Board of Trustees election, see Board vote code. However everything except the candidates names is hard-coded, and there can only be one vote conducted on a wiki at any one time. General approval voting code requires:

• The ability to conduct more than one vote at a time
• The ability for users to start votes
• Flexibility in voting rules including:
  • Who can vote
  • Administration
  • Ending dates or conditions
