    Description

      The Balancer#Parameters class is violating a few checkstyle rules.

      1. Instance variables are not privately scoped and do not have accessor methods.
      2. The Balancer#Parameter constructor has too many arguments (according to checkstyle).

      Changing this class to use the builder pattern could fix both of these style issues.
