/*To make it easier, I will try and implement some more helpers:
- add view before/after existing view (I already mentioned that I think)
- get index of view in its parent
- get next/previous sibling (maybe with an optional argument "type", that might be ImageView.class and gives you the next sibling that is an ImageView)?
- get next/previous element (similar to the above, but would also work if the next element has a different parent, it would just go up the hierarchy and then down again until it finds a matching element)
- find the first child that is an instance of a specified class
- find all (direct or indirect) children of a specified class
