Throw Exceptions for Mock Method Calls

Create a mock for a bank account class.

testCase = matlab.mock.TestCase.forInteractiveUse;
[mock,behavior] = testCase.createMock('AddedMethods',"isOpen");

Specify behavior.

import matlab.mock.actions.ThrowException
import matlab.mock.actions.AssignOutputs
when(withExactInputs(behavior.isOpen), ...
