\class vpMeSite
\ingroup module_me
\brief Performs search in a given direction(normal) for a given
distance(pixels) for a given 'site'. Gives the most likely site
given the probablility from an ME mask
- Bug fix: rewrote application of masks to use the temporal
information instead of applying both temporal masks to the same
image. ie: spatial -> spatio/temporal
- Added new tracking function to choose the most similar edge
amongst all edges found.
- sample step.
