Title: Disable interaction

We have implemented a way to prevent interaction with the elements being 'intro-ed'.
An example use case will be to prevent input in an editor field until the intro is done.

This feature can be switched on or off using the setOption method

Implementation details:
We put a layer above the element that is transparent and has the same size as the helperLayer.
