hasParent
Checks if @file has a parent, and optionally, if it is @parent.
If @parent is null then this function returns true if @file has any parent at all. If @parent is non-null then true is only returned if @file is an immediate child of @parent.
Return
true if @file is an immediate child of @parent (or any parent in the case that @parent is null).
