Changes since 1.9: +2 -12 lines
Switched sense of CPP macro for controlling multi-dimensional advection:
 o DISABLE_MULTIDIM_ADVECTION is set in GAD_OPTIONS.h
 o automatically set if differentiating code
   (comments around call to gad_advection point out how to re-enable it)
 o this avoids needing to add the former macro to CPP_OPTIONS.h
   - reason for this is there's no point in any of the new schemes without it.
