Fix complex samples
One of the possible ways to solve #306 (closed) . It makes the Hamiltonian consistent with the sampels from the Gaussian distribution, but now for complex Gaussian samples
H(s) = -\frac{1}{2}s^\dagger S^{-1} s
<ss^\dagger>=S
is nor satisfied anymore. Instead we have
<ss^\dagger> = 2S
