testing

Added pairwise, as well as a move function that implements pairwise. Tested and everything.
```Java
void move(int fromIndex, int toIndex);
void move(TElement elementToMove, Condition positionCondition, Func defaultFactory)
void move(TElement elementToMove, EqualityComparer equalityMethod, Condition positionCondition, Func defaultFactory)
void move(TElement elementToMove, Selector equalitySelector, Condition positionCondition)
void move(Condition elementsToMove, Condition positionCondition) 
void move(TElement elementToMove, Condition positionCondition, void move(TElement elementToMove, EqualityComparer equalityMethod, Condition positionCondition)
void move(TElement elementToMove, Selector equalitySelector, Condition positionConditionvoid move(Condition elementsToMove, Condition positionCondition)
```

would be the complete list -- because `null` is probably perfectly OK in a number of more object-ee situations.
