Add images to the ViewPickers doc page

[BeksOmega]

What is missing?

There should be images illustrating which view a ViewPicker will pick when presenting with multiple views associated with the same adapter index.

These images should be instantly recognizable, and preferably be edited screenshots taken of one of the test activities. But other more abstract images are perfectly awesome as well.

It would also be nice if the images could be horizontal rather than vertical, so that they fit in the documentation better.

Where should it be added?

There should be an image added at the bottom of the childClosestToMiddle section, and an image added at the bottom of the childClosestToAnchorEdge section.
