this is a error, why there is no class called userItemScalar.java'
add a example to explain the reason and add the
MikeAdaptiveLogisticRegression, in which you can write the own code
instead of use the default code.

just write the code after the super code or remove the super(...)
and write your own code.
move all code in AdaptiveLogisticRegression.java to
MikeAdaptiveLogisticRegression.java make sure it works.
change the code style
