Detailed Description

template<unsigned int N, typename T>
class libMesh::TypeNTensor< N, T >

This class will eventually define a rank-N tensor in LIBMESH_DIM dimensional space of type T. Right now it defines a shim to allow for rank-independent code to compile (but not give correct results) in the case of vector-valued elements and second derivatives.
