* Retrieve all direct and indirect children of the current Checkable. * * Note, this function performs a recursive call chain traversing all the children of the current Checkable * up to a certain limit (256). When that limit is reached, it will log a warning message and abort the operation. * * @param seenChildren - A container to store all the traversed children into. * @param level - The

 * @param level - The current level of recursion.
