|
|
*
|
|
* Framework events handles various mobile browser events, and
|
|
* detects special events like tap/swipe/etc. and emits them
|
|
* as custom events that can be used in an app.
|
|
*
|
|
* Portions lovingly adapted from github.com/maker/ratchet and github.com/alexgibson/tap.js - thanks guys!
