    paper.findViewsInArea(rect [, opt])

Find views (instance of `joint.dia.ElementView`) in a certain area in the paper. `rect` is an object with `x`, `y`, `width` and `height` properties. Return an array of views whose bounding box intersects the `rect` rectangle.
If `opt.strict` is `true`, return an array of views whose bounding box is contained within the `rect` rectangle (i.e. not only intersects it).
