	/// @brief System singleton which represents the PortAudio system.

	///

	/// The System is used to initialize/terminate PortAudio and provide 

	/// a single acccess point to the PortAudio System (instance()).

	/// It can be used to iterate through all HostApi 's in the System as 

	/// well as all devices in the System. It also provides some utility 

	/// functionality of PortAudio.

	///

	/// Terminating the System will also abort and close the open streams. 

	/// The Stream objects will need to be deallocated by the client though 

	/// (it's usually a good idea to have them cleaned up automatically).
