Add atan2 function

[berry hollParticipant]

I am using quite a lot of trigoniometric functions to plot various models in DataGraph, and I am missing the atan2 function in the functions list. Of course it is possible to mimic its behaviour with a chain of conditional expressions, but I guess it might be ‘relatively’ easy to implement this function directly in DataGraph?

We have a function called angle(x,y), which returns the angle for the vector (x,y).  This is equivalent to the atan2(y,x) function that is used in some software.  Sorry if this was not easy to find. We moved the angle function after the atan function in the reference list to help users find this in the future.

Thank you very much for pointing this out, and excuses for not spotting it before. The moving up of angle(x,y) in the reference list and the added documentation relating to atan2 is very helpful too.
