Distillation code that is common across modules
Documentation on how to use this code available at

Notation for (stochastic) DistilParameters taken from 1104.3870:
TI is interlaced dilution in time (corresponding to Nt = time-dimension of the lattice)
LI is interlaced dilution in laplacian-eigenvector space (corresponding to nvec)
SI is interlaced dilution in spin (corresponding to Ns, taken from Grid, usually Ns=4)
This code automatically computes perambulators using exact distillation if
* (TI,LI,SI) = (Nt,nvec,Ns) *
In this case, nnoise=1 and Noises is set to an array of values =1 as well.
tsrc then specifies the only timeslice on which the sources are supported.
(( for stochastic distillation, the vaue of tsrc has no meaning in this code ))
