add functions with TODOs
almost done with API docs
api documentation complete; cvv now shows up in index
in future: write about gui
fix unresolved references by using different (old?) style ones
2.4 -> master:   :ocv:struct:`DMatch` -> :basicstructures:`DMatch <dmatch>`
cmake -DCVV_DEBUG_MODE= only belongs into tutorial
