 /*! \class DelayA
     \brief STK allpass interpolating delay line class.
 
-    This Delay subclass implements a fractional-
-    length digital delay-line using a first-order
-    allpass filter.  A fixed maximum length
-    of 4095 and a delay of 0.5 is set using the
-    default constructor.  Alternatively, the
-    delay and maximum length can be set during
-    instantiation with an overloaded constructor.

-    An allpass filter has unity magnitude gain but
-    variable phase delay properties, making it useful
-    in achieving fractional delays without affecting
-    a signal's frequency magnitude response.  In
-    order to achieve a maximally flat phase delay
-    response, the minimum delay possible in this
-    implementation is limited to a value of 0.5.
