 do nothing, the base class destructor will do the job

 Replace all "<variable>" with "<variable><fAbbreviation>" (Adds forgotten "~")
 but take care on the statistical information, like "CEQmean_Mean"
 and also take care on correct given variables, like "CEQmean~"

 For each variable out of "listOfVariables":
 - 'Save' correct items:
   - form <replaceString>, take <variable>'s first char, add <removeString>, add rest of <variable>, e.g. "C!#EQmean" (<removeString> = "!#")
   - For each statistical information in "listOfNormalizationVariables":
     - ReplaceAll <variable><statistical_Information> with <replaceString><statistical_Information>
   - ReplaceAll <variable><abbreviation> with <replaceString><abbreviation>, e.g. "CEQmean~" -> "C!#EQmean~"
   - ReplaceAll <variable><appendStr> with <replaceString><appendStr>, e.g. "CEQmean.fElements" -> "C!#EQmean.fElements"

 - Do actual replacing:
   - ReplaceAll <variable> with <variable><fAbbreviation>, e.g. "CEQmean" -> "CEQmean~"

 - Undo saving:
   - For each statistical information in "listOfNormalizationVariables":
     - ReplaceAll <replaceString><statistical_Information> with <variable><statistical_Information>
   - ReplaceAll <replaceString><abbreviation> with <variable><abbreviation>, e.g. "C!#EQmean~" -> "CEQmean~"
   - ReplaceAll <replaceString><appendStr> with <variable><appendStr>, e.g. "C!#EQmean.fElements" -> "CEQmean.fElements"

 Now all the missing "~" should be added.

 easy drawing of data, use '~' for abbreviation of '.fElements'
 example: EasyDraw("CETmean~-CETmean_mean", "A", "(CETmean~-CETmean_mean)>0")
 sector: sector-number - only the specified sector will be drwawn
         'A'/'C' or 'a'/'c' - side A/C will be drawn
         'ALL' - whole TPC will be drawn, projected on one side
 cuts: specifies cuts
 drawOptions: draw options like 'same'
 writeDrawCommand: write the command, that is passed to TTree::Draw
