[Insight-users] typo in recently merged code caught by wrapping

[Alexandre GOUAILLARD]

dear hans,

your commit on  itkMattesMutualInformationImageToImageMetric.h
introduced an error in the code line 230 (repeated m_) that was caught
by "Durian" build:
http://www.cdash.org/CDash/viewBuildError.php?buildid=1778539

Unfortunatly I will not have time to work on this this week. Could you
take a look?

alex.
