More specific the logic of DirectionUnitDependetAttributes (DUDA) extending
classes and corresponding Modifier-call methods.
Set the old link<CallMethod> methods @deprecated.
Now you can call an DUDA-CallMethod with either:
- default value (usually number): returns modifier
- nothing: returns DUDA-Ext-Chain
- DUDA-Ext: returns modifier
Introduced mixins to extend DUDA-Extensions with (unified)
returns to modifier or component methods.
Rearanged, added and updated some doc
Moved some of the DUDA-Ext into their own files under src/modifier/.
