v1 of map view and annotation

Hi @litso, @jaaydenh ,

I took a first jab at creating the map view. This is still in experimental mode. So you can take a look but not merge yet. 

1) It loads a map view.
2) Identifies user's current location
3) Drops a pin on it and sets its label to the user text in the text field.

Let me know your comments. Screenshot attached.

Thanks,
Sairam
