Create a project from an existing library with releases

If your existing namespace is a mature library with main, latest, and releases namespaces, you'll will...

1. merge the main subnamespace into the main branch of the project
2. Create a branch called /latest with the branch command and merge the latest namespace into it
3. Each release is a branch with the special form /releases/releaseVersion. Each of the released version namespaces are merged into their respective branches.
