macro replacement for Jacobi elliptic function

[poortho]

{\rm sn}(x,k) -> \Jacobisn@{x}{k}

This is an example with more than one argument.

[poortho]

Does the sn have to be sn or can it be anything else?

Look here:

Then have a look at the paragraph starting with The functions treated

[poortho]

Should I include all of the listed versions or just the three principal ones?

[HowardCohl]

It's not going to matter too much, because this will be handled by the csv file.

So, I think, after you complete this issue, then you can move onto issue #9.

We may need to discuss this, but read the issue very carefully.

Finished with pull request #41

@ClaudeZou @physikerwelt This should be added on the texer repo. Has it?
