Missing documentation for unsupported combination in RandomSplitter

[aleSuglia]

Hello,

using the RandomSplitter I have verified that there is a combination actually not supported (why?) which is not documented. I think that can be useful for users to be aware of this behaviour. In fact, in this case the resulting splits are completely empty and isn't displayed any error message.

See this for reference: https://github.com/recommenders/rival/blob/master/rival-split/src/main/java/net/recommenders/rival/split/splitter/RandomSplitter.java#L99

Cheers,
Alessandro

Thank you for noticing.

Indeed, it is a problem since there is no warning displayed.

Thanks again.
Alejandro
