Hi, while trying to figure out, why `FunctionMultiStore::remove()` is not working correctly (partially my faulty implementation), I discovered that the implementation of our **Copy Assignment Operators** (see also #172, #186) is incomplete. It does not assign any of the members of the `Function` base class: - minLevel_ - maxLevel_ - storage_ - functionName_ - isDummy_ *(do we really need that anymore?)* The implementation of the **Copy Constructor**, however, delegates to the copy contructor of the base class and, thus, does not have this problem.
