/*! \brief The interface to a compound in the object model. 
 *
 *  A compound has a name which can be obtained via the name() method 
 *  and a unique id, which is return via the id() method.
 *  A compound consists zero or more members which are grouped into sections. 
 *  The sections() method can be used to access the individual sections. 
 *  Alternatively, members can be obtained by name or id. There are 
 *  different types of compounds. The kind() method returns what kind of 
 *  compound this is. Depending on the return value one can dynamically 
 *  cast an interface pointer to an more specialised interface that provides 
 *  additional methods.
 *  Example:
 *  \code
 *  ICompound *comp=...;
 *  if (comp->kind()==ICompound::Class)
 *  {
 *    IClass *cls = dynamic_cast<IClass*>(comp);
 *    // use methods of IClass
 *  }
 *  \endcode
 *  The documentation that is provided by a compound is available via
 *  the briefDescription() and detailedDescription() methods.
 *  To avoid excessive memory usage, release() should be called (once) on each 
 *  compound interface pointer that is no longer needed.
