Schema with Builder

Schema works as follows with builder.

Schema sc = new Schema.Builder()
                .addColumnsInteger("Pregnancies","Glucose","BloodPressure","SkinThickness","Insulin")
                .addColumnsFloat("BMI","DiabetesPedigreeFunction")
                .addColumnInteger("Age")
                .addColumnCategorical("Class", Arrays.asList("0","1"))
                .build();

Note: there's only needs a semicolon after the line build().
