There is no default method to generate String

[caelcs]

I tried to generate a String like this

RDG.string(20).next()

But I always have to set the size, and also there is a static field which contain a default. I think that it should be consistent like integer like this:

RDG.String().next()

This makes sense to me. See a quick pull request I've thrown together.

makes sense to me too (was actually surprised we didn't do this!) good catch, thank you.

I think the proper solution though is for all the no-arg methods to return next() from a private static default Generator.

So we'd add a new method string() that would return the string field (that is/should be private final) that is currently there (as per the original issue), but I think we should also add private final static members for Generator<Integer>, Generator<Long>, Generator<Boolean> etc that are used by the relevant no-arg methods rather than creating new generators each time they're called, I think that should just be the standard way to implement a method returning a default generator.

Does that make sense?
