[WIP]Implement attribute assortativity app and numeric assortativity app

[Ningsir]

What do these changes do?

Implement attribute assortativity coefficient app and numeric assortativity coefficient.

• implement C++ PIE app with analytical engineAPI;
• check the correctness with NetworkX
• check the scalability and performance in large graph, like com-friendster dataset
• add to python built-in algorithms and add related test case

@Ningsir Thanks for your commit!
Please assign the related issue in the abstract.

[acezen]

why we nedd numeric_assortativity.h, seems we can reuse the attribute_assortativity.h, please double check?

[acezen]

Can we implement the two algorithms as one app ?
we can send a parameter to check what kind of matrix computation we need

[acezen]

add a p2p test case for attribute assortativity and numeric assortativity like degree_assortativity_coefficient

[acezen]

Overall LGTM.
