The function attempts to determine
whether the input image is a grid of circles. If it is, the function locates centers of the circles. The function returns a
whether the input image contains a grid of circles. If it is, the function locates centers of the circles. The function returns a
non-zero value if all of the centers have been found and they have been placed
in a certain order (row by row, left to right in every row). Otherwise, if the function fails to find all the corners or reorder
them, it returns 0.
