+/**
+ * This utility class will help in Itk::ITestContext implementors to
+ * implement their setup function in a decent manner.
+ *
+ * (1) Initialize all pointers to NULL in the constructor
+ *
+ * (2) define cleanup() that releases / deletes those pointers AND
+ * sets them to NULL
+ *
+ * (3) call cleanup() from tearDown() and the destructor
+ *
+ * (4) In the setup() function, create an instance of this class
+ * template-instantiated for that context class, like
+ *
+ * SetupSentry
+ * ss(*this);
+ *
+ * (5) At the end of the setup function, call
+ *
+ * ss.setupComplete();
+ *
+ * (6) Keep using ITK_PANIC macros as you will (they are implemented
+ * by means of C++ exceptions): the ss instance will call to the
+ * tearDown() (and thus the cleanup()) method, so you don't need
+ * to free / delete / reset to NULL in setup() functions. Also,
+ * one does not need temp auto_ptr-s anymore.
+ *
+ * One would use auto_ptr all around with C++ instances, but many of
+ * the pointers are of the type cpix_XXX *, which do not have
+ * destructors, hence this gadgetry.
