Follow up to XSI -> Houdini and locations

I got some questions after my XSI to Houdini tutorial about the closest location on a geometry from people that didn’t really understand how “xyzdist” could be the same thing as "get closest location" so I thought that I better do a follow up. The big difference is that in XSI a location is just one variable and in Houdini it’s 2 (the Primitive and the uv on that primitive). In XSI you use a ‘Get Data’ node to extract data from that location and in Houdini you use a ‘Primitive Attribute’. I hope that clear things up.
