ELECTRON_FORCE_BALANCE#
struct ElectronForceBalance : public Component#
#include <electron_force_balance.hxx>

Balance the parallel electron pressure gradient against the electric field. Use this electric field to calculate a force on the other species

E = (-∇p_e + F) / n_e

where F is the momentum source for the electrons.

Then uses this electric field to calculate a force on all ion species.

Note: This needs to be put after collisions and other components which impose forces on electrons
