  # Class: Vash (Ruby Volatile Hash)
  # Hash that returns values only for a short time.  This is useful as a cache
  # where I/O is involved.  The primary goal of this object is to reduce I/O 
  # access and due to the nature of I/O being slower then memory, you should also
  # see a gain in quicker response times.
  #
  # For example, if Person.first found the first person from the database & cache 
  # was an instance of Vash then the following would only contact the database for
  # the first iteration:
