  *  @brief Contains the tests for pmNonLinear.c:
  *
+ * test00: This code will create a simple polynomial, and call
+ * pmNonLinearityPolynomial() for a variety of image sizes [(1, 1), (1,
+ * N), (N, 1), (N, N)].  
+ *
+ * test01: This code will create simple table lookup vectors, and call
+ * pmNonLinearityPolynomial() for a variety of image sizes [(1, 1), (1,
+ * N), (N, 1), (N, N)].
