You may ignore terms that appear in the test set but not in the training
set.

In this method, when the term t in the current document has never been
seen before (it wasn't in the training documents) the condprob[t][c] will
be zero, right? Which will break the code as log of zero is illegal. When
this happens, should we just ignore this term and assume we don't add
anything or should something else be done?
