  # select2_ajax helper to make capybara work with ajax-enabled Select2 elements
  # assumes 'placeholder' option is used in Select2 (if it is using ajax, it should be)
  #
  # usage:
  #
  #    it "should have a select2 field for searching by team name" do
  #        @team = Factory :team
  #        select2_ajax @team.name, from: "Select a Team", minlength: 4
  #        click_button "Join"
  #        page.should have_content "You are now on '#{@team.name}'."
  #    end
