Multinomial logloss

Can you use this library to predict multiple classes? The readme hints that you can only predict two classes.

Also, the documentation says that the default value of a missing feature is 1.0. Shouldn't it be 0?

Thanks!

@josepablog For multiple classes, currently it is not. I will add it when I have time recently. Also welcome to contribute.

For default value, it means "1 2:10 3 7:0.5" will means feature 2 has value 10, feature 3 will have value "1", features like 4, 5, 6, will have value 0
