Numerical Columns splitting is not correct

[keckelt]

If there a value is present multiple times, the current algorithm may split at one of these values

The current algorithm does not conider values that occur multiple times and thus may split like:

• Value: 70 Group A
• Value: 72 Group A
• Value: 72 Group A
• Value: 72 Group A -------------------------
• Value: 72 Group B
• Value: 75 Group B

values should be binned like i did in matlab: https://gist.github.com/keckelt/f268ad0d99217c8a77fc7edd24ede461

Count missing values as seperate group, as Ordino also makes a group for missing values.
