VW setting parameters is confusing

[loomlike]

I'm trying to use VW (which is really nice to see from mmlspark!) and setting parameters is somewhat confusing, as some arguments can be set as a builder pattern (setNumPasses and setNumBits) while some should set via setArgs.

It would be nice to be able to use setArgs for all parameters. Then, if I set the same parameter via both the builder and setArgs, I will expect one (maybe builder pattern because I explicitly called) override the other.
