Detailed Description

template<typename T>
class PNOTensors::Tensor_IJ_IK< T >

stores pairs of pairs that share first index (i.e. {ij} and {ik}, where i >= j) as a 3-index tensor: case 1 – i >= j, i >= k: only need j >= k, or ij >= ik; store as {{ij},k} case 2 – i >= j, k > i: can also be found at Tensor_IJ_JK(k,i,j)
