v1.3.1

Full Changelog: v1.3.0...v1.3.1

---

Changed

• Class method add_snapshot now returns graph object for variable assignment (empty by default).
• Parameter delta now explicitly stored as a graph attribute in to_unrolled graphs.
• Refactored neighbors, all_neighbors generators from functions and methods avoiding reduce.
• Refactored node and edge iteration from temporal_{order,size} and degree_centrality.

Fixed

• Calling temporal_{nodes,edges} with copies=False and data=True raised TypeError.
• CollegeMsg and PubMed dataset files (nodes/edges) now included with PyPI package.
• Graph parameters (e.g., name) now preserved when converting from/to multigraphs.
• Import submodule urllib.request for external file downloading, not urllib.
• Parameter index=False for get_{edge,node}_attributes now considered for static graphs.
