/**
  * The description of a generic event. 
  *
  * For now, event parameters are represented exclusively as
  * doubles. This is a simple default implementation, which
  * essentially is little more than a wrapper for an array of
  * doubles. This is more for convenience. It's unlikely that you'll
  * want to use this class yourself; you can do nifty tricks like
  * reformatting the internal representation used in your PEP to
  * provide just one extra method.
