Detailed Description

Langevin part of HMC for conjugate momentum to link variable.

This class implements the Langevin part of the standartd HMC for conjugate momentum to the link variable. The conjugate momentum field is Hermitian and traceless, and set to random values with Gaussian distribution. This class was separated from HMC_Leapfrog (or equivalently HMC_General) so as to implement for general value of Nc. [13 Feb 2013 H.Matsufuru]
