Subject: bug fix in initializing one variable that shouldn't be; parameterizing the CPV method... 
X-Git-Url: http://git.uio.no/git/?a=commitdiff_plain;h=950b56069f7450f0ed532d3e3901b7ecd7b2f11e;p=u%2Fmrichter%2FAliRoot.git

bug fix in initializing one variable that shouldn't be; parameterizing the CPV method of the isoltion clusters to be the same as for the candidate cluster; adding more debugging printouts
