basic json access

I added a file that demos basic json access. Right now it only selects
the first album and continuously loops through all of its images. It
keeps track of how many you get right. It also randomly selects images
from same album to be answer choices. Next steps will be to allow album
choosing, have it end after all images in album exhausted. If somebody
else wants to work on getting the images to distort in another file, we
can integrate once it gets working. Just put this up here for you guys
to look at.
