An element of a sparse tensor in coordinatescheme representation (i.e., a pair of coordinates and value).
For example, a rank1 vector element would look like ({i}, a[i]) and a rank5 tensor element would look like ({i,j,k,l,m}, a[i,j,k,l,m])
The coordinates are represented as a (nonowning) pointer into a shared pool of coordinates, rather than being stored directly in this object. This significantly improves performance because it reduces the perelement memory footprint and centralizes the memory management for coordinates. The only downside is that the coordinates themselves cannot be retrieved without knowing the rank of the tensor to which this element belongs (and that rank is not stored in this object).
