/**
 * This function will crawl through the container essentially check if the children have changed.
 *
 * This function checkChildrenDidChange recursively checks if any child in a Container
 * or its children has changed. It does this by comparing a generated changeId for each
 * child against a stored value in previousData.
 * The changeId is a combination of the child's uid and _didChangeId, bitwise manipulated for uniqueness.
 * If a change is detected, it updates previousData and sets didChange to true.
 * The function returns a boolean indicating if any change was detected in the entire hierarchy of children.
 * @param container - the container to check for changes
 * @param previousData - the previous data from the last check made
 * @param previousData.data - the data array
 * @param previousData.index - the index of the data array
 * @param previousData.didChange - did the data change
 * @internal
