/// @brief A RAII idiom class to ensure automatic clean-up when an exception is
/// raised.
///
/// A simple helper class which uses the 'Resource Acquisition is Initialization'
/// idiom (RAII). Use this class to initialize/terminate the System rather than
/// using System directly. AutoSystem must be created on stack and must be valid
/// throughout the time you wish to use PortAudioCpp. Your 'main' function might be
/// a good place for it.
///
/// To avoid having to type portaudio::System::instance().xyz() all the time, it's usually
/// a good idea to make a reference to the System which can be accessed directly.
/// @verbatim
/// portaudio::AutoSys autoSys;
/// portaudio::System &sys = portaudio::System::instance();
