extends org.apache.hadoop.io.Writable

Payloads for evolutionary state must be copyable and updatable. The copy should be a deep copy unless some aspect of the state is sharable or immutable.

During mutation, a copy is first made and then after the parameters in the State structure are suitably modified, update is called with the scaled versions of the parameters.
