/*! \class ReedTable
    \brief STK reed table class.

    This class implements a simple one breakpoint,
    non-linear reed function, as described by
    Smith (1986).  This function is based on a
    memoryless non-linear spring model of the reed
    (the reed mass is ignored) which saturates when
    the reed collides with the mouthpiece facing.

    See McIntyre, Schumacher, & Woodhouse (1983),
    Smith (1986), Hirschman, Cook, Scavone, and
    others for more information.

    by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
