Operator with a flexible kernel distribution
A random walk operator that selects a random dimension of the real parameter and perturbs the value a random amount according to a Bactrian distribution (Yang & Rodriguez, 2013), which is a mixture of two Gaussians:p(x) = 1/2*N(x;-m,1-m^2) + 1/2*N(x;+m,1-m^2) and more efficient than RealRandomWalkOperator
