fix typo and clean-up in CmakeList.txt
added util.cc and analysis.cc to CMakeList
introduced analysis class

- analysis class stears the analysis in the main file
- it knows about the cuts to be applied, where to write the results
- many functions ported from measurement class to analysis class
minor changes in util class

- ignores entire line when starting with "#" or "["
minor changes in README.md
SignalFinder passes cut values

- instead of passing TCT::analysis object, just pass cut values as floats, avoids circular dependencies
minor change
let analysis object stear the analysis now
