As discovered in #10 , forward-backward will return -INF when given an impossible sequence, as opposed to returning a matrix. Is this okay, or should it return something of the matrix form so that it doesn't crash someones program?
I would say that the i/p and o/p interfaces b/w different components should always remain consistent. Infact, this is also something which needs to be added soon to the docstring.
