The MDS method for gap-filling needs a reorganization. The main reasons or aspects are:

1. introduce the flexibility in the selection of the drivers to be used and tolerances
2. introduce the option to calculate the values to be used for gapfilling considering the uneven distribution of measurements above and below the reference value
3. create the independent tool for this new version (linked and solving the issue Included additional compiled tools for independent steps #14

This issue should be solved adding these options as parameters to pass to the MDS code and then setting them as currently used before switching to new setups.
