// Depends on jQuery.

// Add a child by cloning a template and appending to wrapper element.
// Used with a parent and LazyList of children (One-to-Many).
// Since javascript has no pointers the childCount source var must be incremented by the calling code.
// @param wrapperId The id of the wrapper element, e.g: div or tbody.
// @param cloneId The id of the element to clone.
// @param lazyList The name of the LazyList.
// @param fields A list of fields in the clone that need name and id set.
// @param focusField Which field in the fields list to focus on after adding.
// @param childCount The current child count, used to set LazyList index, remember to increment!
