Cross join implementation has incorrect description of _tableRows

[TylerBrock]

Hey I was just reading through the excellent wiki you've made and I think the comment above row.tableRows = [x, y]; in CROSS_JOIN.md should be: // Store an array of the two rows used to make up this new row. instead of // Store an array of the two columns used to make up this new row.

I sadly don't think there is a way to make a PR against the wiki so I'm filing an issue instead. Cheers!

Great catch. Yeah why can't you make a PR on a wiki? That should be a thing!

Thanks!
