Zero threshold velocity for triggering onSwipeLeft() and onSwipeRight…

…(). Resolves #65.

As pointed out (albeit a bit tersely) in this comment on #65, replacing on-swipe-left with on-transition-left also resolves #65.

I suggest closing this pull request (and #65).

I'm hoping to contributing to the README.md or the ./example (which could use some love). ;)

A swipe will trigger both on-swipe-left and on-transition-left (in that order), so if you are interested in knowing whether it was a swipe or a transition (zero velocity), you'll need to do something like the following:

In the "cards" controller:

  var skipSlow = false;

  $scope.cardTransition = function(dir, speed, index) {
    console.log('BrowseCtrl .cardTransition', dir, speed, index, skipSlow);
    if (speed === 'fast') {
      skipSlow = true;
      $scope.addCard();
    } else if (!skipSlow) {
      $scope.addCard();
    } else {
      skipSlow = false;
    }
  };

Repeater directives (some omitted for clarity):

<td-card ng-repeat="card in cards" on-swipe-left="cardTransition('left', 'fast', $index)" on-transition-left="cardTransition('left', 'slow', $index)" on-swipe-right="cardTransition('right', 'fast', $index)" on-transition-right="cardTransition('right', 'slow', $index)">
