This PR introduces initial version of einsum operator to SystemDS. Einsum operator follows structure of Numpy einsum https://numpy.org/doc/stable/reference/generated/numpy.einsum.html For tests, R package einsum https://cran.r-project.org/web/packages/einsum/einsum.pdf is used Implemented so far: validation of einsum instruction preprocessing: simplifying inputs by contracting dimensions that can be contracted at the beginning preprocessing: identifying diagonal of matrix plan generation plan execution using individual operands (matrixMultiply, multiply, transpose, sumR, sumC, sumAll) fallback: Cell template with for-loops for einsums that cannot be solved using further 2D summations (e.g AB,BD->ABD) (M Thesis at TU Berlin "Efficient Einstein Summation in Apache SystemDS") -- This is an automated message from the Apache Git Service.
