Modules
module	mod_kdv
	Module for including kdv source term in simulations adds \(-\delta^2*\sum_i \partial_{iii} \rho \) over dimensions i.

Functions/Subroutines
subroutine	mod_kdv::kdv_params_read (files)
	Read this module's parameters from a file.
subroutine	mod_kdv::kdv_init ()
	Initialize the module.
subroutine	mod_kdv::kdv_add_source (qdt, ixil, ixol, wct, w, x, qsourcesplit, active)
	w[iw]=w[iw]+qdt*S[wCT,qtC,x] where S is the source based on wCT within ixO
subroutine	mod_kdv::kdv_get_dt (w, ixil, ixol, dtnew, dxd, x)

Variables
logical	mod_kdv::kdv_split = .false.
	source split or not
double precision	mod_kdv::kdv_delta = 1.0d0
	forefactor \( \delta^2\) of \( \partial_{iii} \) term
integer	mod_kdv::kdv_order = 1
	switch for second order [1] or fourth order [2] central FD for \( \partial_{iii}\) Note: fourth order needs 3 nghostcells, all assume equidistant grid
