// A: It isn't generic and breaks encapsulation. Also, using string
// name comparison is not reliable, since you can't guarantee that
// no one else will name their custom module "Quadric".
// Q: What should be done instead?
// A: ModBaseT API should support modules that can be both binary
// and priority, or BETTER YET, let the DecimaterT API specify the
// priority module explicitly.
// find the priority module: either the only non-binary module in the list, or "Quadric"
