Add indoor map information #8
Description
As a user I would like to show indoor information for the target buildings as the user walks in their boundaries. It should:
- Switch to an indoor map (we recommend to use GroundOverlay) as the user walks inside the boundary.
- Allow the user to switch the floor displayed for the building
- Show an indication of available indoor maps (optional).
- Automatically change the floor using the barometer information (optional)
