new $verticalSwipe()
The $verticalSwipe service is a service that abstracts the messier details of hold-and-drag swipe
behavior, to make implementing swipe-related directives more convenient.
Requires the module to be installed.ngTouch
$verticalSwipe is used by the ngeoSwipeUp and ngeoSwipeDown directives.
Usage
The $verticalSwipe service is an object with a single method: bind. bind takes an element
which is to be watched for swipes, and an object with four handler functions. See the
documentation for bind below.
