44 * FunctionDefinitionHomogeneousSimple is an abstract class, so we have to test it by creating a sub-class.
45 * The constructor is tested by default when an instance of the sub-class is created for other tests.
47 * Each of these functions needs to be tested for each type of function to be sure the values are correct,
48 * so this is just a simple test to see that the mechanism works.
51 * In Eclipse select this file or the enclosing directory, right-click and select Run As/JUnit Test
