Decision Tree select minimun number of records per node

This workflow makes a plot based on "the minimun records per node" parameter that helps to define the size of a decisión tree and its accuracy error

At the beggining the user can define a list of numbers that defines "the minimun records per node" and then executes a loop that collects the error rate, for that parameter.

The idea is to check in the scatter plot if there is an "optimal" "the minimun records per node" parameter given the error decrease in the decision tree
