/**
* Handle two synchronized sequences.
*
* This method is called by a {@link ReplacementsFinder ReplacementsFinder}
* instance when it has synchronized two sub-sequences of object arrays
* being compared, and at least one of the sequences is non-empty. Since the
* sequences are synchronized, the objects before the two sub-sequences are
* equals (if they exist). This property also holds for the objects after
* the two sub-sequences.
*
*
* The replacement is defined as replacing the {@code from}
* sub-sequence into the {@code to} sub-sequence.
*
*
* @param skipped number of tokens skipped since the last call (i.e. number of
* tokens that were in both sequences), this number should be strictly positive
* except on the very first call where it can be zero (if the first object of
* the two sequences are different)
* @param from sub-sequence of objects coming from the first sequence
* @param to sub-sequence of objects coming from the second sequence
