Class ConditionalGrounding

public class ConditionalGrounding
extends PropertyGrounding

Provides a grounding for a resource object that matches if another column is true using SMALLINT == 1 as a boolean true value. This is useful for grounding statements like: ( ) only if some other column is true. TODO: this can be abstracted further so that any condition (using the Match class) can be used as the condition.
