> Not sure we should do this, it costs 5-10% performance for WFSTSuggester.
> But maybe we can optimize something here, or maybe its just no big deal to us.
> Because in general, this could be pretty powerful, e.g. if you needed to store 
> some custom stuff in the suggester, you could use pairoutputs, or whatever.
> And the possibility we might need shortestPaths for other cool things... at the
> least I just wanted to have the patch up here.
> I haven't tested this on pairoutputs... but i've tested it with e.g. FloatOutputs
> and other things and it works fine.
> I tried to minimize the generics violations, there is only 1 (cannot create generic array).
