Introduce Assertion

A section of code assumes something about the state of the program.

Make the assumption explicit with an assertion.
        double getExpenseLimit() {
                // should have either expense limit or a primary project
                return (_expenseLimit != NULL_EXPENSE) ?
                        _expenseLimit:
                        _primaryProject.getMemberExpenseLimit();
        }

        double getExpenseLimit() {
                Assert.isTrue (_expenseLimit != NULL_EXPENSE || _primaryProject != null);
                return (_expenseLimit != NULL_EXPENSE) ?
                        _expenseLimit:
                        _primaryProject.getMemberExpenseLimit();
        }
