Left-to-right beam search decoder

Nettetbeam search decoder that finds a translation that approximately maximizes the conditional proba-bility of a trained NMT model. The beam search strategy generates the translation word by word from left-to-right while keeping a fixed number (beam) of active candidates at each time step.
