Additions:
- Now doing also tex tables of prefit/postfit with uncertainties ready to be added to a document
- added some more plotting options -- see README
- almost all channels from combination are doable, missing only bbgg. It still misses the functionality of plotting a function from the WS.
Examples of plot results and tables to the combination channels are here $DHI_STORE/Prefits/Plots_demo_2, where $DHI_STORE is the /eos we are using for sharing the combo results.
Next MR it will be integrated to a task.
