I'd like to use your library, but I'm lost without an example to get me started.

I have several pages in my app, and I would like to be able to swipe left and right to go from one page to another.

These pages have their own modules with a "Show" public sub that can be called from other pages.

Correct if I'm wrong, but I assume I have to initialize a GestureRecognizer object in each of the page modules?

I tried it on my own, but I couldn't make it work. I might not have initialized the GR object correctly.

An example would be very nice :)

Thank you!
