Derive and implement derivative kernels for B-mode potential #11

Open mdschneider opened 8 years ago

We need options to simultaneously model E and B mode potentials (leading to E and B mode convergence fields).

A straightforward to derive this could be to replace the real-valued potential with a complex-valued potential and then keep track of all the real and imaginary parts (real being E-mode, imaginary being B-mode).
