<W> is a primary observable

several functions, needs testing

Now model labels in plots

Bayesian averaging method supports now averaging over two fit functions

Bayesian average method for one fit function added to juobs_tools.jl

fluc_obs computed twice

error finding non-defined id

dec_const uses time reflected correlators

broadcasting dictionaries is not allowed

update in getall_eigvals and uwerr(ydata) removed in juobs_tools.jl/fit_routine in order to choose a different wpm windows. Otherwise it does not work

dec_const uses time reflected correlators

automatic truncation t0 + unfinished runs
