The key value is position.

Following is a sample JSON:
 u'location':{
         u'lat':u'2',
         u'position':u'+2.00000+77.00000/',
         u'lon':u'77',
         u'objectType':u'place'
      }

Fixes issue #28 in a much more saner way.

Few exception handling bugs fixed.

Ignore rules updated.
