Language corrections on latest Geo doc pages (Android)

Hi. I reviewed the Geo docs for Android in a similar way as what I did in my last pull request for all Android docs.
These are my comments:
1) I recommend using GeoPoint everywhere constently instead of Geo Point for the element and Geo Point for the class for the sake of simplicity (same for the rest of Geo elements).
2) Also recommend using "object/s" and not "Object/s" when referring to Kii objects to avoid confusion with the Object class (Java)
3) I recommend adding an explanation of lat & long notation used (degrees with decimal fractions). For more info see what you can get from here: http://www.satsig.net/lat_long.htm
