cvAdaptiveskinDetector revisited

Exploring the purpose of histogramHueMotion in cvAdaptiveSkinDetector, noticing that the effect even with a weight value of 0.05 being accounted when being mergeWith() the skinHueHistogram. Tested with a video in 'Office' settings. The outputHueMask is able to cover the human faces more completely, and inevitably covers more areas of similar color tone, like the wall. Perhaps it's the surface of the human faces giving a range of hues that spreads  the adaptive-ranges in findCurveThresholds(), and that in turns pick up more pixels as skin.
