Comment (by dcoudert):
Hello,
I have improved the cost computation. It is now incremental and so faster.
I don't see how I can avoid the cimport of popcount32. If I want to reuse
the `find_order` method from `vertex_separation`, I need a .pxd file.
Since `FastDigraph` is an input parameter of the method, it should appear
in that .pxd file, right?
Do you have a better solution in mind? The only alternative I see is to
not share the code.
For the fuse type / template stuff, since now the methods have different
inputs, it is may be too complicated for the possible benefit. You agree?
David.
