hcurl_curl_operator.cpp

Using PipelineManager interface calculate the curl of base functions, and integral of the vector tangent vector with normal on the boundary. Since the h-curl space is used, volume integral and boundary integral should give the same result, as a result, as we are applying Stokes theorem on h-curl space.
