Moved setup function into top level __init__
Discovered that the remote module also relies on the git executable assuch it also needs to be “refreshed” anytime the git executable isupdated or changed. This was best solved by moving the setup functioninto the top level __init__ where the setup simply callsgit.cmd.Git.refresh and git.remote.FetchInfo.refresh.
