Detailed Description

template<class Cell1T, class Cell2T, class CoefT>
class tTensor< Cell1T, Cell2T, CoefT >

Tensor of chains.

This is in fact a chain made up of pairs of cells of the given type. One can add products of chains to the tensor, which is then decomposed into tensors of individual cells and reduced.
