    instances represent method-category changes (as done in the browser). 

    They are typically held in a ChangeSet.

    Change origin.

    When a changeset diff is generated, two MethodChanges that 

    represent the same method (code is the same) might differ only in

    category/ Such changes are transformed to MethodCategoruChanges.

    In that case, origin keeps the reference to original MethodChange.
