Example: You have a branch refactor that is quite different from master. You can't merge all of the
commits, or even every hunk in any single commit or master will break, but you have made a lot of
improvements there that you would like to bring over to master.
Note: This will not preserve the original change authors. Only use if necessary, or if you don't mind losing that information, or if you are only merging your own work.
On master:
> git co -b temp
