[Eeglablist] Interpolation Documentation

The spherical interpolation we use is the standard one. Here are the references.

However, my PI wants to see some documentation of how interpolation works, specifically for the "Spherical" option. I know that the code for that function is available, but is there any more theoretical/methodological documentation for interpolation?
