/// @brief Class which represents a PortAudio device in the System.
///
/// A single physical device in the system may have multiple PortAudio
/// Device representations using different HostApi 's though. A Device
/// can be half-duplex or full-duplex. A half-duplex Device can be used
/// to create a half-duplex Stream. A full-duplex Device can be used to
/// create a full-duplex Stream. If supported by the HostApi, two
/// half-duplex Devices can even be used to create a full-duplex Stream.
///
/// Note that Device objects are very light-weight and can be passed around
/// by-value.
