Purpose of This Thorn
---------------------
The Multipole thorn performs spherical harmonic mode decomposition of
Cactus grid functions on coordinate spheres. It can decompose
multiple grid functions with any spin-weight on multiple spheres.
This thorn uses the interpolator interface to access grid functions,
so works with mesh-refinement and multi-patch.

Required thorns
---------------
* An interpolator, e.g. AEILocalInterp

Related thorns
--------------
* WeylScal4 can be used to compute the Weyl scalars, which can then be
decomposed into modes on coordinate spheres by Multipole.
