Detailed Description
Utility class to calculate the "fingerprint" of a simulation.
We are trying to achieve that the same simulation gives the same fingerprint on a 32-bit machine and on a 64-bit machine. Longs can be either 32-bit or 64-bit, so we always convert them to 64 bits. We do not try to convert endianness, it would be too costly.

Converts the given string to a numeric fingerprint value.
The object is not changed. Throws an error if the string does not contain a valid fingerprint.
