sumpy: n-body kernels and translation operators

sumpy is mainly a 'scaffolding' package for Fast Multipole and quadrature methods. If you're building one of those and need code generation for the required multipole and local expansions, come right on in. Together with boxtree, there is a full, symbolically kernel-independent FMM implementation here.

It relies on

• boxtree for FMM tree building
• loopy for fast array operations
• pytest for automated testing

and, indirectly,

• PyOpenCL as computational infrastructure
