Multiple vars and arrays using PythonFile

Right now there isn't any syntax for returning multiple variables/arrays back at once, only one of each. However, I can think of two ways to do this, usually I do (1):

1. After running `PythonFile`, make a second call to `Python` that doesn't run any code, but simply requests the variable or array. You can do this any number of times.

PythonFile file = "script.py", var = {"pyvar1", igorVar1}, array = {"pyArray1", igorWave1}
Python var = {"pyvar2", igorVar2}, array = {"pyArray2", igorWave2}

2. If you're trying to return more than a couple arrays/variables, you might be better suited to create a wave reference wave from Python, put the arrays inside it, and return that to Igor as a single wave. The same could be done with your variables, by packing them into a wave. You still might be left making multiple calls to `Python` though. For instance, you'd do something like this in Python and then return the `refs` wave back to Igor.

refs = igorpro.wave.create('waverefs', shape = 2, type = igorpro.wref)
refs[0] = igorpro.wave.createfrom('w1', pyArray1)
refs[1] = igorpro.wave.createfrom('w2', pyArray2)

Hope that helps
