Getting Number of Items

Thank you for great library, I think SimplePagination.js is great.

This is not an issue, but feature request (I don't know how to raise a feature request, please let me know if there is a way to do this on GutHub).

I use your library, and in my case needed a way to get the number of items... this was needed for updating the pagination... in my local project, I added a function to your library, to get the number of items:

[getItems: function () {
var o = this.data('pagination');
return o.items;
}
](url)

I think it would be useful to add this function to the library.

Thank again for great work,

Start in SimplePagination.js and inspect how the pagination data is exposed. Add the requested getItems entry point so it returns the number of items, then verify that the plugin's existing behavior remains intact.
