Detailed Description

Implements the makeNonce function in the same way as the original implementation of makeNonce within Helper.cxx.

To operate a farm/cluster of UASs/proxies, you must:

1. make sure the clocks are sychronized (using ntpd for instance)
2. use the same privateKey value on every instance of the application

To operate with SER, use the SERNonceHelper instead, as that generates the nonce string the same way as SER. You must also observe the same conditions above regarding clock and key synchronization.
