/**
 * triggers a callback when an element gets into the viewport
 * uses a little bit of jQuery. elements auto receive the class `inview`
 *
 * the threshold parameter is on scale from 0 to 1 of the height.
 * 0 means it triggers directly, 1 means it must be full visible
 *
 * @example
 * // images needs to be 50% in view
 * inview.register("img", .5, function(item, inview_state) {
