currently our $near syntax : { loc :

{ $near : [0,0], $maxDistance : 3 }

} forces us to add each $near parameter to the general parsing logic - should really be like $within:

find({ loc : { $near :

{ $center : [[0, 0], 3] }

})

This will let us add $uniqueDocs more easily to $near : so:

find({ loc : { $near :

{ $center : [[0, 0], 3], $uniqueDocs : true }

})
