#define F14_MODIFIERS_RARE "EeWwAaSs" //expdef would need to handle these properly/specifically to ensure reasonable behavior, and hardly any expdef does. Modifying initial energy of a creature as a result of its genes (Ee) is in general not a good idea. Weight (Ww) works only in water, and in water sinking/going up should usually be caused by real "intentional" activity of a creature, not by its inherited weight. For assimilation (Aa), there is a dedicated parameter in CreaturesGroup. Stamina (Ss) is no longer needed as destructive collisions are not supported, and even if they were, some expdef would need to impose reasonable restrictions on the value of this parameter (e.g. similar to normalizeBiol4()) so there is some cost associated with it, and the specific consequences of destructions should be defined as needed.

 * usually affects further sticks, so new sticks should have properties of
 * parents (prop) modified with the prop.propagateAlong() method.
 * "Biological" properties (assimilation, stamina, muscle strength and
