Detailed Description

template<typename T_ansatzsp, typename T_testsp, typename T_value = double>
class Hpro::TLaplaceDLPBF< T_ansatzsp, T_testsp, T_value >

     TLaplaceDLPBF implements the bilinear form for the Laplace
     double layer potential with the kernel function
     \f[ \frac{\langle n(y), y-x \rangle}{\|x-y\|_2^3} \f]
     or the adjoint potential
     \f[ \frac{\langle n(x), x-y \rangle}{\|x-y\|_2^3} \f]
