Currently the skin map routines attempt to make a skin map even when we know it won't work/won't be right.
I would like for it to (by default at least) stop at the earliest opportunity. For example if it is not a Siemens unit, or there are non-Cu filtrations in use.
In the situation where you have a mix of Siemens systems and others, you may want skin maps switched on but not to slow the system down attempting failed calculations for the other systems.
I can also see that you may want to make it easy to let them calculate for anyone who wants to investigate how to develop the software further, but that shouldn't be the default situation.
I don't know if this is in @dplatten's code or the original @jacole openSkin code. Maybe it could be achieved by creating a dummy calc file when testing for height and weight etc in
rf_detail_view_skin_map if we also test for Siemens etc in that section.
I'd also appreciate @LuukO's view on this.
