> Do we really need to import sage.graphs.generators.chessboard at
startup?
I don't know.
Following Jeroen's suggestion, I have created a new directory to store
graph generators instead of continuously increasing the size of
sage.graphs.graph_generators.py. Later, we could split the
graph_generators file and create smaller files, easier to read, faster to
test, etc. in the generators directory.
Now, the question is how to make these functions accessible from graphs
(e.g., graphs.QueenGraph()) without importing the file at startup. Is
there a way to import them the first time they are used? or any other
interesting trick I'm not aware of?
