[Sidefx-houdini-list] How would you import multiple attributes into vex... arrays?

If the list of points is presented as geometry attributes, then you  
simply need to have parameters with matching names, and they'll  
automatically be set to the geometry attribute value.  Unless you use  
arrays, that means 18 extra parameters.

Another approach, now that I think about it (I don't have Houdini in  
front of me), is to simply use the import() function just get point/ 
attribute values.
