return true if set correctly, false on failure (if node==NULL || i is out of range).
When set can be successful applied, the algorithm is : decrement the reference count origNode and increments the

to force it to recompute on next getBound() and returns true.
If origNode is not found then return false and do not
add newNode. If newNode is NULL then return false and do
