def initialize( match_or_matches=nil, opts={} )
  ## fix:
  # passing in e.g. pts for win (3? 2? etc.)
  # default to 3 for now

  ## lets you pass in 2 as an alterantive, for example
  @pts_won = opts[:pts_won] || 3

  @lines = {}   # StandingsLines cached by team name/key

  ## add init and update all-in-one convenience shortcut
  update( match_or_matches )  if match_or_matches
end
