Design simplifications and nomenclature changes

- Future Ans compressor will be a black box, meaning that there is no need on sharing 'Rle' and 'ZigZag' functions, or an identical loop procedure ('IterateLifts').
- Still, the loop procedure stays, as can be useful when implementing the '-ratio' option in the library itself.
