Mark,

I'm going to second this request, especially since you've made the QuadTree
private (in r846). I was relying on directly modifying the QuadTree when I
needed to remove an object from a GeomVectorField, since no remove method
was provided.

I now have a temporary workaround by having an "unauthorized trunk" of
GeoMASON where I've made the QuadTree public again (I suppose I could also
have just added my own remove method, but wanted to keep the change
typographically light). But I'd be much happier to use an approved remove
method.

Thanks!
