/**
 * assertContains(

 *      string $message = '']
 * )
 * 
 * Reports an error identified by $message if

 * assertNotContains() is the inverse of this 
 * assertion and takes the same arguments.
 * 
 * assertAttributeContains() and assertAttributeNotContains()
 * are convenience wrappers that use a public, protected, or 
 * private attribute of a class or object as the haystack.
