SYNOPSIS

           $rv = deepCopy($sourceRef, $targetRef);

DESCRIPTION

       This module provides data manipulation functions, which at this time only consists of
       deepCopy.

SUBROUTINES/METHODS

   deepCopy
           $rv = deepCopy($sourceRef, $targetRef);

       This function performs a deep and safe copy of arbitrary data structures, checking for
       circular references along the way.  Hashes and lists are safely duplicated while all other
       data types are just copied.  This means that any embedded object references, etc., are
       identical in both the source and the target, which is probably not what you want.

       In short, this should only be used on pure hash/list/scalar value data structures.  Both
       the source and the target reference must be of an identical type.

       This function returns the number of elements copied unless it runs into a problem (such as
       a circular reference), in which case it returns a zero.
