=head1 DESCRIPTION

This module makes doing experiments with Maximum Entropy learner easier.

Generally, an experiment involves a training set and a testing set
(sometimes also a parameter adjusting set). The learner is trained with
samples in the training set and tested with samples in the testing set.
Usually, 2 measures of performance are concerned.
One is precision, indicating the percentage of samples which are correctly
predicted in the testing set. The other one is recall, indicating the 
precision of samples with a certain label.
