Mathematica is a useful tool for analyzing coupled ordinary differential
equations (e.g., phase plots, stability analysis, etc.); however, does
anyone know of an elegant way to analyze delay-differential equations
using Mathematica?  Numerical techniques require using a ringbuffer to
store past values.  I am not aware of a built-in function do this in
Mathematica; having to create a ringbuffer array manually may preclude
the benefits of using Mathematica over other numerical integration
