// If you want to use the JER code in standalone mode, you'll need to create a new define named 'STANDALONE'. If you use gcc for compiling, you'll need to add
// -DSTANDALONE to the command line
// In standalone mode, no reference to CMSSW exists, so the only way to retrieve resolutions and scale factors are from text files.
