Postprocess a Reaction-Eikonal model.
-------------------------------------
This example shows how to postprocess a full heart reaction eikonal model.

Create a postprocessor object
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. note::
   This example assumes that you have you ran a full heart electrophysiology simulation
   and that the d3plot files are located in ``data_path``.
