Added onTransitionLeft, onTransitionRight and onTransitionOut

Added these functions to fix an issue where a drag passed the threshold
needs to behave like a swipe in that direction.
<td-card
on-transition-out="cardTransitionedOut(amt,$index)"
on-transition-left="cardTransitionedLeft($index)"
on-transition-right="cardTransitionedRight($index)”>
….
</td-card>
