public abstract class Blocking
extends java.lang.Object
```
Generic class to check if an _individual in an completion graph is _blocked by another _individual. Blocking prevents infinite models to be created and can improve performance by limiting the size of the completion graph built.

This abstract class defines the basic functionality needed to check for blocking and leaves the actual check of blocking _condition between a pair of individuals to its concrete subclasses that may do different things based on the expressivity of the _current kb.
