changes since 0.13.0
===================================
NEW 2015-02-13 first implementation of a standalone Fourier transform/plotter:
musrFT. Initially it is meant to be used for HAL-9500,
i.e. Fourier transform WITHOUT lifetime correction.
A first simple minded lifetime correction is implemented as well.
NEW 2015-01-17 adding a branch for ROOT 6.x. This needs some minor adaptations due
to the new rootcint/rootclang and the stricter c++11.
NEW 2014-12-18 first implementation of a GLOBAL block which allows to shorten

### Contents ###
This is a data analysis package to analyze time differential muSR data.
This is a data analysis package to analyze time differential muSR and beta-NMR data.
Currently it allows the following things:
* setting up most commonly used fitting functions for muSR
* setting up most commonly used fitting functions for muSR and beta-NMR
* fitting data, including global fits
* showing the fit results and the residuals
* showing the Fourier transform of the data
