WIP ShipStudio FreeCAD 1.0 Testing Smoothing Input Data and Rebuild Master Curves

I was experimenting with my thought how to read data from the spreadsheet workbench and smooth the data (original data was already smooth) and at the same time reducing the amount of data. At the end of the process is to be able to extract bsplines poles and show it in the 3 viewer. From 22 points every single bspline reduced to 6 where on the next process is building a 6x7 surface grid.
Sometimes I want to be able to tweek the hull produced by another program in FreeCAD.
Watch the correlation of the distribution of the poles and the isocurves. It says a lot.
A lot of function already build during these years. My functions are those on the top and bottom of the FreeCAD window.
