@fspindle Should I make the vpParticleFilter class a template class to allow
having other types than vpColVector for the measurements ?
It would affect the signature of the vpLikelihoodFunction but would have no other
effects on the class.
It would permit to use e.g. a pcl::PointCloud for the measurement instead of having to convert it
into a vpColVector. However, as far as I know, template classes are not allowed in Python, so the
Python wrapping would be limited to vpColVector.
