Description (last modified by ncohen)

From the docstring : A graph is a Gallai tree if and only if it is connected and its 2-connected components are all isomorphic to complete graphs or odd cycles.

This patch also slightly touches the function is_clique, which was unnecessarily copying the whole graph 2 times :

  • Firstly, using the subgraph method
  • Secondly, using the to_simple method
