A few suggestions

[webbby]

Hey good job with the lib.
May I suggest a few relatively easy features.

1. Could you add to dragStart, dragEnd event callbacks a direction arg
2. Also disableRight and disableLeft methods which disable movement in one of the directions

In my case I don't want a user to be able to progress right until conditions are met so that would be very helpful feature.

Thank you for your time BR
