Detailed Description

template<typename T_ansatzsp, typename T_testsp>
class HLIB::THelmholtzDLPBF< T_ansatzsp, T_testsp >

     THelmholtzDLPBF implements the bilinear form for the Helmholtz
     double layer potential with the kernel function
     \f[ \frac{e^{i \cdot \kappa \|x-y\|_2} (i\cdot \kappa \|x-y\|_2 - 1) \langle n, y-x \rangle}{\|x-y\|_2^3} \f].
