Added all of the bike stations, with location marker icons.
Added map markers for each station. Changed map marker image from stars
to location markers. Added dialog window for bike checkout. Still need
to implement onClick for map markers.
onTap for markers is now working. Currently just brings up a Toast
message with the location title.
Markers now bring up a dialog when clicked.
Removed dialog fragment. Changed some formatting.
