  /**
   * MKS Integrity implementation for Maven's AbstractChangeLogCommand
   * <br>Currently there is a limitation in the 'si rlog' command where changes
   * can't be limited to a normal/variant/build configuration.  In other
   * words all revisions modified within the date range will be picked up
   * for the Change Log report.  By default the Change Log is grouped by
   * Change Package ID.  However, if no Change Package is found or Change
   * Packages are not in use, then all the changes are grouped in one big
   * Change Log Set
