<p>Pointer to a vector factory that is used to create child list vectors for any child nodes that need them. </p>
<p>This means that we auto track the vectors and auto free them when we close the factory. It also means that all rewriting trees can use the same tree factory and the same vector factory and we do not dup any nodes unless we must do so explicitly because of context such as an empty rewrite stream and ->IMAGINARY[ID] so on. This makes memory tracking much simpler and tempts no errors. </p>
