class Puma::Single

This class is instantiated by the `Puma::Launcher` and used to boot and serve a Ruby application when no puma “workers” are needed i.e. only using “threaded” mode. For example `$ puma -t 1:5`

At the core of this class is running an instance of `Puma::Server` which gets created via the `start_server` method from the `Puma::Runner` class that this inherits from.
