Depth first traversal for intersection in lttoolbox (C++)
completed by: Matthew
mentors: Kevin Brubeck Unhammer, Francis Tyers
https://github.com/unhammer/lttoolbox/tree/df-intersection contains a stub function in transducer.cc called "intersection". The main loop needs implementing.
This task is not to do the actual intersection, but to traverse the states of the two transducers in parallel, only following an arc from this transducer if there is a matching one from the current (set of) live states in the other transducer.
Come on IRC to discuss this task http://wiki.apertium.org/wiki/IRC
