Merge FixVisualizer into HistoryMapActivity (in progress).
Ensure "no title bar" works as intented.
Ensure date picker doesn't not fade out during processing.
Upgrade to Java 7 as I don't see why not.
No marker rendering is done in MapHistoryActivity.
Leave FixVisualizer just for reference now.
Improve UI response time by using AsyncTask for reading in the fixes.
