{** Determines if one path is the child of another path.
*
* Matches the start of two normalized paths. Either of the path may contain
* parent-references (ex. 'some\..\..\path\'). Note that the file system is
* not actually accessed, all checks are performed on the strings only.
*
* The parameters are modified to return the expanded file names, stripped
* of any trailing path delimiter.
*
* @param AChild the path to check
* @param AParent the path which is supposed to be the parent
* @result True if the child is indeed a child of the parent,
* False otherwise.
