Dense tensor class.
| rank | rank of the tensor, i.e. number of dimensions |
| Scalar | Scalar type of the tensor, i.e. the type of individual entries |
As a rule, legs are 1-indexed, i.e. if one wants the dimension of the first leg, one calls dim(1). Elements are 0-indexed, i.e. the first scalar in the top leftmost corner sits at coordinate [0, 0, …, 0] and offset 0.
