Remove predictors and responses because they don't need to be stored by the

Refactor LogisticRegression class. LearnModel() can be private, and we can
...
const-ize a lot of the parameters and functions. Also restore functionality to
Predict(), ComputeError(), and ComputeAccuracy(). This does not ever make a
copy of the predictors matrix and doesn't add a column for the intercept, which
is faster.
