Detailed Description

Random noise source in the space at a given timeslice.

Random noise source in the space at a given timeslice src = \eta_{i_color,i_spin}^{i_noise}(x), where \eta is a random number field satisfying \sum_{i_noise} \eta^{i_noise} = 0 \sum \eta_i^{i_noise,\dagger} \eta_j^{i_noise} = \delta_{ij} [10 Jan 2017 Y.Namekawa] Add two functions set_all_space_time(ic), set_all_space_time(ic,is) intended to be used in VEV calculation with fermion_flow.
