Error in surface curl function

Dear Bempp team,

I think there is an implementation error in the surface_curl function of the bempp.api.space.FunctionSpace class in Bempp-cl 0.3.1. There are two input arguments missing in the returned numba_surface_curl function, namely local_multipliers and normal_multipliers. Moreover, the input argument element should not be there – it seems to be a relic of the old BEM++. Thus, the surface_curl function is not applicable. Or am I not seeing this correctly?

Moreover, I am wondering, why such a surface curl is only defined for SNC and (consequently) for NC spaces and not also for the other vector spaces.

Thank you kindly in advance.

Best regards,
Raphael
