Fixed the notification screen for my tablet(the accepted location
request title did not show centered)
Fixed issue with empty step instructions(people in the same room can get
locations without crashing)
Made it so old polylines from previous located person route goes away
when new route is created
Got rid of the Test cases in the Menu and put in "Directions" which
should only work when a route is displayed(we can change this into a
button that appears instead)

Either much later tonight or tommorow afternoon, I will comment all of
my code
