//Description:
// Purges an instance definition and its definition geometry.
//Parameters:
// idef_index - [in] zero based index of instance definition to delete.
// This must be in the range
// 0 <= idefIndex < InstanceDefinitionTable.Count
//Returns:
// True if successful. False if the instance definition cannot be purged
// because it is in use by reference objects or undo information.
//bool PurgeInstanceDefinition( int idef_index );
//Description:
// Purge deleted instance definition information that is not
// in use. This function is time consuming and should be used
// in a thoughtful manner.
//Parameters:
// bIgnoreUndoReferences:
// If false, then deleted instance definition information
// that could possibly be undeleted by the Undo command
// will not be deleted.
// If true, then all deleted instance definition information
// is deleted.
//void Compact( bool bIgnoreUndoReferences );
//Description:
// Undeletes an instance definition that has been deleted by DeleteLayer().
//Parameters:
// idef_index - [in] zero based index of an instance definition
// to undelete. This must be in the range
// 0 <= idefIndex < InstanceDefinitionTable.Count
//Returns:
// TRUE if successful.
//bool UndeleteInstanceDefinition( int idef_index );
//Description:
// Read the objects from a file and use them as the instance's
// definition geometry.
//Parameters:
// idef_index - [in]
// instance definition index
// filename - [in]
// name of file (can be any type of file that Rhino or a plug-in can read).
// bUpdateNestedLinks - [in]
// If true and the instance definition referes to a linked instance definition,
// that needs to be updated, then the nested defition is also updated.
// If false, nested updates are skipped.
//Returns:
// True if successful.
//bool UpdateLinkedInstanceDefinition(
// int idef_index,
// const wchar_t* filename,
// bool bUpdateNestedLinks
// );
//Description:
// Gets an array of pointers to layers that is sorted by
// the values of CRhinoInstanceDefinition::m_sort_index.
//Parameters:
// sorted_list - [out] this array is filled in with
// CRhinoInstanceDefinition pointers sorted by
// the values of CRhinoInstanceDefinition::m_sort_index.
// bIgnoreDeleted - [in] if TRUE then deleted layers are filtered out.
//Remarks:
// Use Sort() to set the values of m_sort_index.
