/**
 * More complex assertions can be formulated using the PHPUnit_Framework_Constraint 
 * classes. They can be evaluated using the assertThat() method. 
 * Example below shows how the logicalNot() and equalTo() constraints can be used 
 * to express the same assertion as assertNotEquals().
 * 
 * assertThat(mixed $value, PHPUnit_Framework_Constraint $constraint[, $message = ''])
 * Reports an error identified by $message if the $value does not match the $constraint.

 * ==> Constraint that asserts that one value is identical to another.
 * 
 * PHPUnit_Framework_Constraint_IsFalse isFalse() 	
 * ==> Constraint that asserts that the value it is evaluated is FALSE.
 * 
 * PHPUnit_Framework_Constraint_IsInstanceOf isInstanceOf(string $className) 	
 * ==> Constraint that asserts that the object it is evaluated for is an 
 *     instance of a given class.
 * 
 * PHPUnit_Framework_Constraint_IsNull isNull() 
 * ==> Constraint that asserts that the value it is evaluated is NULL.

 * PHPUnit_Framework_Constraint_IsTrue isTrue() 
 * ==> Constraint that asserts that the value it is evaluated is TRUE.
 * 
 * PHPUnit_Framework_Constraint_IsType isType(string $type) 	
 * ==> Constraint that asserts that the value it is 
 *     evaluated for is of a specified type.
 * 
 * PHPUnit_Framework_Constraint_LessThan lessThan(mixed $value)
