1) I don't think you have to register a stat before you use it in a formula. If you do, that should be pretty easy to undo. Also, formulas define +=, so you could define Formula in the base class, and use += to add child values from the child class. The order of construction is the same order as init functions. Generally, we initialize from bottom up. So, regStats should be called from bottom up. (Cycles will mess this up).
2) If you don't give a statistic a name, then it won't get printed.
