This widget allows you to display position information from your
GPS-receiver. It also can display the position on openstreetmap and
perform reverse geocoding through geonames.org

- set_browser: Sets the path to the www-browser. If no browser is
set the default is /usr/bin/uzbl
- set_device: Sets the GPS device ie. /dev/rfcomm0 if you have a
bluetooth GPS receiver. Default is /dev/rfcomm0
** Usage
Include the following line into your rc.lua :
```lua
local gps = require("obvious.gps")
```lua
Then set the device and the browser:
```lua
gps.set_device("/dev/rfcomm0")
gps.set_browser("/usr/bin/uzbl")
```
And add it to your wibox's widgets list:
```lua
gps()
```
