-> new base class InputType is used throughout the decoder
instead of Sentence
Sentence and ConfusionNet derive from this class
-> Manager etc. do not know if the input is a sentence or a
confusion net (but could check if REALLY needed)
- two separate classes derived from TranslationOptionCollection:
one for text input and one for confusion net input
- score computation in PhraseDictionaryTree.cpp and some optimizations
