Method analyze not public in abstract class Transducer

[johann-petrak]

This means that the abstract base class cannot be used to use a model without caring if it is weighted or unweighted. If there is a good reason why this is not public it should be documented, otherwise the method should be made public in the abstract class.
I also do not understand why this is an abstract class rather than an interface, its only purpose seems to be to declare the common useful method of all transducers (weighted and unweighted) which is really the job of an interface.

I made a patch/pr before noticing this

Any progress on this? Omorfi Java interface compilation fails because Omorfi tries to extend analyze.
