Code to simplify task-parallel programming in Java by wrapping the
built-in executor framework.  Also, given code for graphical heat
diffision application.  This code is described in
a) Paper "Using wrappers to simplify task parallel programming" by
   Michael Graf and David P. Bunde.  Appeared in Proceedings of the
   Consortium for Computing Sciences in Colleges Midwestern conference
   (CCSC-MW), 2014.
b) Poster "Accessible parallel programming in Java" by Michael Graf
   and David P. Bunde.  Presented at the 4th NSF/TCPP Workshop on
   Parallel and Distributed Computing Education (EduPar), 2014.

The code comes in 2 packages:
1) SimpleExecutor: The wrapper code to present a simple work queue
   implementation based on the executor framework in
   java.util.concurrent.  Contains the following:
   a) SimpleExecutor: wraps an ExecutorService
   b) SimpleTask: Class to extend in order to create tasks.  Simply
      extend it and override the run method with the desired
      operation.
   c) SimpleFuture: Returned by SimpleExecutor when it is asked to run
      a Callable (a task with a return value).

2) SerialHeat: A serial implementation of a heat diffusion
   simulation.  Intended as given code for an assignment with which to
   use the (wrapped) executor framework.  The main function is in
   GUI.java.
