I'm wondering why we have these methods @ChrisRackauckas ? this does not make sense in general, only maybe for 2 operators

What's a case where they don't make sense?
The reason I have done this is that operators are often combined together, so the elements of differentials are not necessarily differentials, but can in general be other functions too. |

Stale, someone would need to revive it. |

Adds Vector calculus operators which are composable by the dot and cross product.
A request for comment on a good design so that equations with these display intelligibly
