Cleaned up some code for the Travler, TravelerGroup, and
TravelersDbAdapter.
Traveler README
Other Traveler Notes
Created a working DbAdapter Base Class

The DbAdapter class is meant to inherit to all DbAdapter (i.e.
TravelerDbAdapter). TravelerDbAdapter (in this commit) is a working
example of this inheritance format.
v5 Code Cleanup for DbAdapter and Others

Cleaned up all current code for branch merge.
v6 Handles Rotation

Previously, app would crash on TravelerDialogFragment rotation. Now, it
handles the rotation and also rearranges elements within the dialog.
v6 Part 2 (GitHub error?)

This files didn't go through in the last commit...
