Bu::Heap is a real class, it works great, except it doesn't grow right now.

I'm thinking the heap should add one layer to the binary tree each time it
grows, which means double+1 each time.  The Bu::ItoHeap will be implemented as
soon as the rest of Bu::Heap is done.

Also, I finally added bu/util.h which is mainly handy template functions like
Bu::swap, Bu::min, Bu::max, and Bu::mid.  A few more may be added.
