Added one function (setup) and an alias (refresh simply calls setup).These functions give the developer one more way to configure the gitexecutable path. This also allows the user to interactively adjust thegit executable configured during runtime as these functions dynamicallyupdate the executable path for the entire git module.

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.

Renamed to simplify and avoid issue with nose tests trying to use`setup` as a setup for testing. Unittest implements basic test forrefreshing with a bad git path versus a good git path.

Added my name to list.

Added the ability to silence the first refresh warning upon import bysetting an environment variable.

Renamed GIT_PYTHON_NOWARN to GIT_PYTHON_INITERR and added values forquiet import, warning import, and raise import. These respectively meanthat no message or error is printed if git is non-existent, a plainwarning is printed but the import succeeds, and an ImportErrorexception is raised.

Removed few remaining references to git.setup function (as it wasrenamed to refresh).

Renamed and cleaned up variable names.

Added additional information in the import warning/error that tells theuser how to silence the warning/error. Also added a GIT_OK variablethat allows for a quick check whether the refresh has succeeded insteadof needing to test an actual git command.

Added tilde expansion as part of the refresh function. Added pythonversion check such that we properly capture PermissionError in Python>=3 and OSError in Python <3.
