Add data manager module and fence support to navigator
- Add function to geo.c to determine if global position is inside fence
- Add navigator support/commands for maintaining fence coords.
- Add data manager module to support persistence fence storage. Can
store other data, but only used for fence at this time.
- Add unit tests for data manager
