/*
   Non-Interpolating Delay Line
   Object by Perry R. Cook 1995-96.
   Revised by Gary Scavone, 1999.
   Added methods by Julius Smith, 2000.

   This one uses either a delay line of
   maximum length specified on creation
   or a default length of 2047 samples.
   A non-interpolating delay line is
   typically used in non-time varying
   (reverb) applications.
