/// @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).
