Modifier class abstract

The specification of a collision modifier.

A collision modifier defines a method to modify the position of mark items, avoiding visual overlapping.

Modifiers could be customized by extending this class. Although all aesthetic encodes can be modified in a modifier, only the position is recommended. Rendering customization should be in the Shape.

Note that the modifier should be functional, which means to return a new groups list as result, not to change the input groups.
