Error: The type or namespace name 'RectangleTrack' does not exist in the namespace 'OpenCVForUnity' (are you missing an assembly reference?)

Can not find RectangleTrack in OpenCVForUnity namespace. OpenCVForUnity : 2.5.4/2.6.2

It is true that the namespace of the “RectangleTrack” class is “OpenCVForUnity.RectangleTrack”. It seems that this is due to the fact that the code was created a long time ago. At least, no error occurs in our environment at present. However, if there is a possibility of some side effects, we will consider changing it to “HoloLensWithOpenCVForUnityExample.RectangleTrack” etc. in the next update.
