Todo says "show head image" instead of "show body image"

[singhofmarco]

In lesson 2 Fragments, the checklist says "display the first image of in the list of head images" but the class should be body_part_fragment. I think this is a mistake. Very minor one though.

In my opinion, I think the body part fragment refer to head, body and leg. When you do the exercise add three fragments, you will notice we use BodyPartFragment for showing head, body and leg.
