/**
* Implements the functionality that is needed to hold options and option

* Tool to this class.
*
* This class is intended to be used as base class for all MBS grammar
* elements that can hold Options and Option Categories. These are currently
* Tool and ToolChain.
*
* Note that the member <code>superClass</code> must be shared with the
* derived class. This requires to wrap this member by access functions
* in the derived class or frequent casts, because the type of <code>superClass</code>
* in <code>HoldsOptions</code> must be <code>IHoldOptions</code>. Further
* note that the member <code>resolved</code> must inherit the value of its
* derived class. This achieved through the constructor.
