First steps towards ARM
Interface of timedep calculating the correct weighting factors
Fixed the weighting factors
Take out of range situations properly into account: forcings series may
be shorter than run time
Test with moist hydrostatics in anelastic scheme
Use half level pressure in buoyancy tend instead of interpolated full level press.
Running ARM case
Fixed a few more settings
cleanup of code, to-do: extend calcbasestate() to 4th order scheme
Proper transformation velocity in arm case
Merge branch 'time' into anelasticupstream
Merge remote-tracking branch 'bart/anelastic' into anelasticupstream
