/// @brief Wrapper for PortAudio error codes to C++ exceptions.
///
/// It wraps up PortAudio's error handling mechanism using
/// C++ exceptions and is derived from std::exception for
/// easy exception handling and to ease integration with
/// other code.
///
/// To know what exceptions each function may throw, look up
/// the errors that can occure in the PortAudio documentation
/// for the equivalent functions.
///
/// Some functions are likely to throw an exception (such as
/// Stream::open(), etc) and these should always be called in
/// try{} catch{} blocks and the thrown exceptions should be
/// handled properly (ie. the application shouldn't just abort,
/// but merely display a warning dialog to the user or something).
/// However nearly all functions in PortAudioCpp are capable
/// of throwing exceptions. When a function like Stream::isStopped()
/// throws an exception, it's such an exceptional state that it's
/// not likely that it can be recovered. PaExceptions such as these
/// can ``safely'' be left to be handled by some outer catch-all-like
/// mechanism for unrecoverable errors.
