Re: histogram subtraction and mean

I've had trouble with mean of subtracted histogram calulated by root .. it's just plain wrong. Error very noticable when histogram is not near sysmetric, but people might be fooled when it is reasonably sysmetric. I just wrote my own mean calculatator based on bin content.

Default should be fixed to do something reasonable.
