rewrite loop in unfold using matrix algebra (Davide's suggestion) and actually use dirname as argument of validation.plot(..)
implement background smearing (to be optimized!)
version bump
provide background with norm uncertainty
rewrite loop in unfold using matrix algebra (Davide's suggestion) and actually use dirname as argument of validation.plot(..)
implement background smearing (to be optimized!)
version bump
provide background with norm uncertainty
add initial values to nuisance parameters and plot traces wity mcplot
add plots of traces and autocorreleation
Merge branch 'background' of https://github.com/gerbaudo/fbu into background

Conflicts:
	fbu/PyFBU.py
	fbu/validation.py
plot background trace only in summary
use N 1D stochastics instead of size=N stochastics
set starting point in the middle of the hyperbox
allow arrays of lower and upper bounds
use lower and upper as a list
provide lists of upper and lower to fbu
add plot comparing data and background
add geweke and raftery-lewis tests
initialize lower and upper as lists
