SLU12 : exercise 3

[TiagoFerrao]

The name of the columns above the exercise :
''create a new field called **discrete_votes** which is the discretization of the Votes field, such that the range is between 0 and 49 and the original instances are uniformly distributed;
create a new field called **binary_votes** which is the binarization of the Votes field, such that amounts smaller than 100 become 0 and amounts equal or greater than 100 become 1."
do not match the ones on the comments of the same exercise :

create new column discrete_amount using suitable transformer
create new column binary_amount using suitable transformer
