/** This class measures the negative log likelihood. In fact, it supposes
that for each input frames, frames[i] is the log-probability for class $i$.
The given #class_format# gives the class format of the targets of the dataset.
By default, the measurer divides the log-probabilty by the number of examples
and the number of frames.
