-modifying the stop marker loader class to load stops from external source and than load from local DB after
-by removing the persistence to db from load the processes has improved to load time to less than 5sec
-storing to db part will be done on the background thread after the markers are loaded and sent back to the UI.
-had to synchronize the "add all stops to db" because cursors are not thread safe and were throwing concurrent errors on Nexus
