Sensor Tile

Sensor Tile is a easily handle and self-illustrate colorful tools, it have the following functions:
-Compass, so we can know the orientation.
-GPS, so we can know where we are, the longitude, latitude, altitude(if support, works in Nexus5)
-Atmosphere pressure, environment brightness and temperature(if support).
-Battery status
And here is the cool feature(In my opinion): every sensor is a tile with different background color. We can turn on or off the sensor by just double-click it. And can change the tile position by drag it too.
