Instead we're going to move back to standard exceptions.
Using a custom Result class has created far far more problems
- The Stacktraces aren't always right
- Sometimes one forgets to check the Result error
- All other exception throwing code needing to be converted to Results
- Non idiomatic Dart code
I think it's better to just go back to exceptions. They have their
problems, but overall, I think it's a better approach.
I want the git_setup code to only have the UI. Nothing else. The cloning
process for GitJournal is very specific to GitJournal. It doesn't need
to be that complicated for other projects.
