Title: - added a variable 'absNLL' to the output tree of MultiDimFit

to contain the absolute negative log likelihood ratio
(not sure though it is filled for all methods, we used
it with --algo=grid).

We (Xiaohang and me) have used this for the width studies
to compare different sets of parameters (scaling the sigmas of the
Voigtians) to the SAME dataset and used it to detect overfitting
of the data (due to mass peaks in the signal model which are
too narrow and lead to a high local s/b ratio)

Originally based on HiggsAnalysis-CombinedLimit-V03-01-09 but
rebased on the latest head.
