What a new session is created as, including its first window.

tmux always creates a first window, so the fields naming one are not optional in effect — leaving them empty takes tmux's defaults rather than creating nothing.

## Members

- `name` (attribute)
- `start_directory` (attribute)
- `first_window_name` (attribute): The name of the window the session starts with.
- `shell_command` (attribute)
- `width` (attribute): The size tmux gives the session while no client is attached.
- `height` (attribute)
- `environment` (attribute): Variables the new process starts with, on top of what tmux passes down.
