     27 	///
     28 	/// The System is used to initialize/terminate PortAudio and provide 
     29 	/// a single acccess point to the PortAudio System (instance()).
     30 	/// It can be used to iterate through all HostApi 's in the System as 
     31 	/// well as all devices in the System. It also provides some utility 
     32 	/// functionality of PortAudio.
     33 	///
     34 	/// Terminating the System will also abort and close the open streams. 
     35 	/// The Stream objects will need to be deallocated by the client though 
     36 	/// (it's usually a good idea to have them cleaned up automatically).
