Enhancements to Matrix Functions

[pelesh]

Several enhancements to matrix operations including:

• Checks if data already exists when setting matrix and vector data. If so, report error.
• Export Re::Solve matrices to MatrixMarket file format.
• After deleting matrix data set data pointers to null.
• Add print functions to Csr and Csc matrix classes.
• Closes #122.
• Adds ILU0 factorization on CPU and appropriate unit test.
• Add hijacking constructor to CSR matrix class.

Code builds cleanly on x86_64 and AMD GPUs. All tests pass (run manually, CI pipelines are broken).

When I am trying to compile, I am getting linker error [ 78%] Linking CXX executable version.exe In file included from /people/swir617/ReSolve/tests/unit/matrix/runMatrixIoTests.cpp:7: /people/swir617/ReSolve/tests/unit/matrix/MatrixIoTests.hpp: In member function ‘ReSolve::tests::TestOutcome ReSolve::tests::MatrixIoTests::cooMatrixExport()’: /people/swir617/ReSolve/tests/unit/matrix/MatrixIoTests.hpp:89:37: error: ‘max_element’ is not a member of ‘std’ 89 | const index_type N = 1 + *(std::max_element(rows.begin(), rows.end()));

Can be fixed with #include <algorithm>

LArge example works correctly.

All tests passes successfully. Looks good to me.
