busclique._regularize_embedding hangs occasionally #215

Closed boothby closed 2 years ago

We introduced the busclique.mine_clique_embeddings function in #214, and it failed once during testing. I turned logging on for appveyor tests, and the problem occurred again in #99. This results from the progress variable not being reset in the main loop of the _regularize_embedding function.
