1.2

Using the new particle shape factor implementation, we now redistribute particles only at the end of each timestep instead of at every runge-kutta stage (#50).
Removed WarpX bilinear filter, since we don't need it to get stable evolution. Emu now does not include any WarpX code (#49).
Removed WarpX shape factors. Wrote new shape factor implementation in ParticleInterpolator so we now can evolve particles within ghost cells (#48).
We now determine the shape factor order taking into account both the user-specified order and the dimensionality of the problem so we use order 0 in the directions where the domain contains only one cell (#47).
Fixed issue with flavor vector length so we can now run simulations with nonzero initial amounts of non-electron flavor neutrinos (#44).

1.1.1

Emu has been through the LBNL licensing process for open source code. We release Emu under the BSD-3-Clause-LBNL license, the code is identical to v1.0.

Version of Emu used for paper 1 Particle-in-cell Simulation of the Neutrino Fast Flavor Instability (https://arxiv.org/abs/2101.02745)
