Parameters:

groupsize	the maximum numbers of interest points in a group
groupsizeseedsearch	number of neighbourgh interest points of a group used to compute the first match
minimalgroupsize	the minimum numbers of interest points in a valid group
distance	the maximum distance between the center of a group and the other members (we use norm 1)
closeness	the threshold above which we can consider that two descriptors are describing the same interest point (maximum value is 1.0)
weakcloseness	the threshold for the comparison of the weakComparison (maximum value is 1.0)
distinguability	the distinguability is use when we search the first match (the seed) to determine if two hypothesis are different enough
rotationTolerance	the tolerance on the change of rotation in a group between reference and match
scaleTolerance	the tolerance on the change of scale in a group between reference and match
distanceTolerance	the tolerance of change in the translation vetween ref and match when trying to restart a propagation after running the tree has stop
rotationDifferenceWithMedian	once we have tried to match all group, we compute the median of the rotation to eliminate the outliers
thresholdofenoughtgroup	determine the minimum number of group left below which we won't try to find a new seed when the propagation is stopped (between 0.0 and 1.0, note with 0.0 no seed will ever be searched)
matchFocus	this object will control the
