swipe gesture set up

[broken build] - the coredata will crash on the swipe off of the
predictive search result

[changes]
Swiping works well, like I envisioned it initially. Stubbed in the
indicator views that tell the user s/he can add/reduce debt with the
swipes/pans.
Cleaned up a bit.
Getting ready to branch to moving the coredata singleton into the
appdelegate. Just makes more sense that way.
