//// Baseclass CValue

//// Together with CExpression, CValue and it's derived classes can be used to

//// also expandible by a CFactory pluginsystem

////
|
|
//// Features:
|

//// Reference Counting (AddRef() / Release())
|
|
//// Calculations (Calc() / CalcFinal())
|
|
//// Configuration (Configure())
|
|
//// Serialization (EdSerialize() / EdIdSerialize() / EdPtrSerialize() and macro PLUGIN_DECLARE_SERIAL
|
|
//// Property system (SetProperty() / GetProperty() / FindIdentifier())
|
|
//// Replication (GetReplica())
|
|
//// Flags (IsSelected() / IsModified() / SetSelected()...)

////
|

//// Some small editor-specific things added
