AvoidUnusedPrivateFieldsRule Class

This rule checks all private fields inside each type to see if some of them are not being used. This could be a leftover from debugging or testing code or a more serious typo where a wrong field is being used. In any case this makes the type bigger than it needs to be which can affect performance when a large number of instances exist.
