/**
* A UniConf generator that replicates generators between an ordered list
* of inner generators, with the priority given by the list.
*
* Replication of the data occurs when the generator is contructed, whenever
* prepend() or append() is called, or whenever any of the generators in the
* list goes from !isok() to isok(). If two inner generators contain different
* values for the same before replication, then they will both have the value
* of the earlier generator (as ordered in the moniker) after replication.
*
* If an asynchronous change occurs in any of the inner generators, the
* new value will be set in all generators irrespective of priority.
