```
src.WorkspaceBuilder.build(self, workspace: &Workspace) -> Result<Session, BuildError>
```

Create the session a workspace describes, and return it.

Windows and panes are created in the order the configuration lists
them. Nothing is attached: the caller decides whether to take over a
terminal.

# Errors

Returns an error when a session of the same name exists, or when tmux
refuses any step.
