checkGetterAndSetter
Checks if methods such as get.MyProperty() and set.MyProperty() have
been declared. The rationale behind this check is that nothing should
happen when you set or get a property when it is used directly to make
sure that the code stays readable and does not produce any unexpected
side effects. If it is necessary that actions are performed when getting
or setting a property, make the property private and implement explicit
getters and setters (for example getMyProperty() and
setMyProperty()).
