Change index ordering in rtvd related routines. Thanks go to Mariusz Mamoński for pointing that out
Introduce new variable for controling Fast Eulerian Transport for differentially rotating disks (aka FARGO)
Merge branch 'rtvd_ordering' into fargo_merge
Add additional keyword to 'relaxing_tvd' that allows to skip applying source terms
Introduce new module for governing FARGO related bits
Include additional time constraint for FARGO algorithm
Allow to advect fluid quantities with arbitrary velocity instead of the one computed directly from momentum
Add enumerator type used to discern between residual and constant residual velocity in fargo
whitespaces
whitespaces
Implement sweeps scheme for FARGO
cleanup
[fargo] cleanup, add missing assignment to cg
Final touch to rtvd in order to make FARGO working
