I'd like to modify a project before its sources are parsed and cached. My
purpose in doing this is that because all files are parsed on startup, opening a
project takes 5-10 minutes with our source tree. Many folders can be added to
Exclude roots, however, and I'd like to do this before they're ever parsed.
However, it looks like projectOpened isn't called until after files are parsed,
and I don't know how else to get a hold of a Project instance to modify it. Is
there a way to do this?
