 * The QGLikelihoodCalculater calculates the likelihood for a jet
 * It takes information on the valid range of the tool, the binning of the categories, and their PDFs from the QGLikelihoodObject
 * The variables in the vars vector should match with the variables in the QGLikelihoodObject, in which they are identified by the varIndex
