NodeUnion is a templated helper class that controls access to either the child node pointer or the value for a particular element of a root or internal node. For space efficiency, the child pointer and the value are unioned, since the two are never in use simultaneously. Template specializations of NodeUnion allow for values of either POD (int, float, pointer, etc.) or class (std::string, math::Vec, etc.) types. (The latter cannot be stored directly in a union.)
