helperSanitizeBoxes is a function provided in some object detection examples but is not a built-in function?

I've been working with the object detectors and some of the supporting functions call "helperSanitizeBoxes" which I assume helps with bounding boxes overextending the image dimensions. I've tried looking up this function, but am curious if anyone has insight into what it does/how it can be released.

The function helperSanitizeBoxes is used to clean up invalid bounding box data. Boxes with values <=0 are removed and fractional values are rounded to integers. If none of the boxes are valid, this function passes the data through to enable downstream processing to issue proper errors.
For more information about this function you can run the following example where you can open the helperSanitizeBoxes.m file available in current folder section:
