Term ooc covariance tsmm

[122Astha]

I added the initial OOC covariance test setup for cov(A, B). The test creates dense and sparse vector inputs, runs the covariance script once as the CP reference and once with -ooc, then compares the results.

Currently both dense and sparse OOC tests fail for the expected Week 1 reason: SystemDS generates an OOC cov instruction, but OOCInstructionParser does not support Covariance yet. The key error is: “Invalid OOC Instruction Type: Covariance”. This confirms the test-first setup is working and identifies the missing implementation/wiring.

Thanks for the first PR, @122Astha. I’d suggest working on the covariance implementation before opening a PR. It isn’t necessary to open PRs just to introduce failing test cases.

Please configure your IDE to use tabs instead of spaces (and remove hello.dml).

Thanks for the changes. Could you please address the codestyle and license issues (tabs instead of spaces, add license on top of each file)?

Please remove hello.dml as well as the markdown files.
