Add ability to show arrow

[Misiu]

First of all thank You for creating this project, it fills perfectly the gap in material 2.

I'd like to ask for restyling popover so it looks more like one used by google.

and below is current style:

As You can see arrow is missing.
Small border around popover and arrow would make it more clear.

I have one additional question: When using Google Maps we have 3 icons in top right corner. Clicking on each one opens popover in exact same place, only arrow position indicates what button is "attached" to that popover. Is same approach possible with Your component?
