tfbi_theory + SymSolver

Joint repository containing two Python packages: tfbi_theory and SymSolver tfbi_theory solves the linear theory of the Thermal Farley-Buneman Instability (TFBI). Internally, relies heavily on SymSolver. Available on pypi: https://pypi.org/project/tfbi_theory/ SymSolver provides a Symbolic Solver for system of equations, system of linear differential equations, first order plane wave perturbation dispersion relation. Available on pypi: https://pypi.org/project/SymSolver/ Version number of this repository corresponds to latest released version number from both packages. (Future versions of this zenodo repository may need to update this note if tfbi_theory and SymSolver version numbers ever diverge. These packages are no longer under active development, so the joint repository versioning hopefully will remain simple enough.)
