Another step of trying to clean up the underlying tool (ElectronEfficiencyCorrection-00-01-85)

	* tagging ElectronEfficiencyCorrection-00-01-85
	* Another step of trying to clean up the underlying tool
	* There were major usage of pointers , whilst not necessarily needed.
	* Use less pointers, less naked news.
	* Hopefully will make maintanance easier.
	* This is the 3rd take to clean this up (taking into accout optimisation related ones).
	* Hopefully, there will be only minor leaks left,
	* and perhap we can try another take on speading it up
