FeaturePoint struct

[chris-wei-17]

Hi Zhengao,

In feature.h you create a struct FeaturePoint and define variables oldFeaturePointsLeft and currentFeaturePointsLeft in main.cpp, but it doesn't appear that these variables are ever used. I am assuming the intention of this was to be used to describe features with unique identifiers and age, as described by Fig. 2 in the Cvisic paper. Can you confirm that this struct is not used? It appears that feature age is implemented in the FeatureSet struct, but that features are identified by row when necessary

Thanks,

Chris
