optimization of the algorithm when dealing with empty bins in the tails of the pdf's\r\n* Some clean-up and optimizations on the QGLikelihoodDBWriter code (the input src files and created QGL_v1.db

PR includes a 'shape' change in the CondFormats class QGLikelihoodObject: the data member Entry::mean has been removed. \r\n\r\nUnfortunately this type of change CAN'T BE ALLOWED for persistable classes. The reasons are:\r\n- there are currently at least two payloads of this type in the DB, that won't be readable anymore after the change\r\n- the current and older CMSSW versions will still produce payloads having this data member.\r\n\r\nThe proposed solution, if this data member 'clean up' is really required, is to create a new CondFormats, mapped to a new Record.\r\n\r\n"}}
