added main menu added debug display many debug widgets for plotting live data worked on android live sensors added offline-data sensor feeding some dummy data sensors worked on the map display added ui debug for grid-points, particles and weights added a cool dude to display the estimation added real filtering based on the Indoor components c++11 fixes for android compilation online and offline filtering support new resampling technique for testing map loading via dialog
