e4deea4b94 Weird bug appears with Vector<Vector<>>. 
"fix" with std::vector<Vector<>>

Lies in the face table code. But think there is some latent problem.
Possibly in my allocator since it is caching, but could simplify or eliminate the caching
option and retest. One to look at later.

6d58cb2a68 Enable reordering of the loops in the assembler for cache friendly. 
This gets in the way of L2 prefetching however. Do next next link in stencil
prefetching.
