Carrier
In this exercise you'll create a StringIndexer and a OneHotEncoder to code the carrier column. To do this, you'll call the class constructors with the arguments inputCol and outputCol.
The inputCol is the name of the column you want to index or encode, and the outputCol is the name of the new column that the Transformer should create.
