> This epic aims to introduce code generation capabilities for automatic operator fusion,
which helps to reduce the number of materialized intermediates, reduce the number of input
scans, exploit sparsity, and reduce compute, while significantly reducing the development
effort compared to hand-coded fused operators. 
> For the 1.0 release, we will introduce code generation as an experimental feature, covering
an extended version of SPOOF's code generator as described in the following paper:
> T. Elgamal, S. Luo, M. Boehm, A. V. Evfimievski, S. Tatikonda, B. Reinwald, P. Sen: SPOOF:
Sum-Product Optimization and Operator Fusion for Large-Scale Machine Learning, CIDR, 2017
