Analysis using results of previous analysis
This branch enables running analyses using results of previous analysis. This is needed to do N-point scans for strip readout chips, but could be useful in other scenarios.
A dummy NPointGain analysis algorithm, which would use the results from ScurveFitter, is added to demonstrate the idea. But since the n-point scan depends on the strip threshold scan, it might be better to merge this after the relevant loop actions and scans for strips are included in devel.
