+Fixed: Manifold::get_new_point() previously ignored points weighted negatively.
+The original intent was to avoid to divide by a 0 weight, but the condition
+weight < tolerance resulted in ignoring negative weights.
+Additionally, the same function previously avoided get_intermediate_point()
+when the weight of of the first point was 0, but forgot to assign the new
+intermediate point to be the second point.
+The issues would mainly occur for derived Manifold classes that only implement
+the get_intermediate_point() function. Both issues are now fixed.
