Detailed Description

curl (alpha curl E) + beta E = rhs

Here E is an Array of 3 MultiFabs on staggered grid, alpha is a positive scalar, and beta is either a non-negative scalar or a MultiFab.

It's the caller's responsibility to make sure rhs has consistent nodal data. If needed, one could call prepareRHS for this.

The smoother is based on the 4-color Gauss-Seidel smoother of Li et. al. 2020. "An Efficient Preconditioner for 3-D Finite Difference Modeling of the Electromagnetic Diffusion Process in the Frequency Domain", IEEE Transactions on Geoscience and Remote Sensing, 58, 500-509.
