Save Set information for repeated Processes

When setting up a recurring Process that uses a Set with different values each time, Rosetta does not keep a record of the Set values each time it is generated, so that you cannot Rerun the previous Process instances in History. We propose a change to the recording of Set metadata so that each time a Set is used, its values are stored, thus allowing a Historical Process to be rerun at a later date. An example is rolling fixity checks, wherein a different range of SIPs are checked each day using the same Process. By saving the SIP range each time, any Process instance in the History can be rerun if necessary at a later date.
