示例1: merge

* Takes collection of policies and merges them into a single policy using algorithm described in
* WS-PolicyAttachment specification. None of the original policies in the collection are modified in
* any way.
*
* The newly created policy has an ID that is a concatentation of all merged policy IDs.
*
* @param policies collection of policies to be merged. The collection must not contain '{@code null}' elements!
* @return merged policy containing combination of policy alternatives stored in all input policies.
* If provided collection of policies is {@code null} or empty, returns {@code null}. If provided
* collection of policies contains only single policy, the policy is returned.
