获取开始节点下一步待选节点：
  是否属于多次实例化配置（dynamic动态实例化配置：结合办理人动态生成待办节点）
    t:无需检查是否到结束标识，所以按配置的重复实例化策略结合当前操作人生成待办节点，如：生成x级部门办理，下一接口再选具体部门
    f:开始节点配置的下一节点集合

获取开始节点所选下一步节点的具体参数：
  是否属于多次实例化配置
    t:所选x级部门返回对应办理对象集合(具体部门)
    f:按模板配置返回办理对象集合

获取待办节点下一步待选节点：
  是否属于多次实例化配置（无需检查definetion,直接找到当前待办节点获取参数（需要的参数冗余至待办节点上））
    t:检查是否到结束标识（检查当前办理节点的办理对象与结束标识(orglevel:int)是否一致）
      t:返回配置的下一节点(看作单次实例化，当前节点已办完)//definitionId,stepCodes，按配置走
      f:按配置的重复实例化策略结合当前操作人，生成如：{x:X级部门办理},{0:中心办理},最高级最多只能到中心，按动态策略走,动态策略枚举
  是否处于会签中
    t:按会签策略的下一级 + 上一级（isCSEnd会签汇总节点标记）,并对上一级选项打上标记，如：{x:X级部门办理},{0:中心办理},按动态策略走，动态策略枚举
    f:按照definition(按配置走)
  返回当前节点的配置下一步

获取下一步的具体参数：
  检查模式
    按动态策略：依据当前操作人、动态类型枚举 查询对应待选部门
    按配置策略：原有实现方案

start:
  check配置是否允许当前用户发起

next: (nextStepCode/x, userId[]/orgId[],dto.other)
  check该不该当前用户办(handlers，all不需要check)
  办理当前节点
  创建后面节点
    是否动态实例化
      t:检查是否到结束标识(参数orgId==mark?)
        t:(参数时stepcode)按配置创建
        f:(参数是x级部门)按动态实例化策略创建
    是否处于会签中
      t: 是否返回上一级汇总 (isCSEnd)
        t:  1.update上一级的会签完成情况[]
            2.如果会签全完成，创建新的待办汇总节点(IsCountersignSummaryStep = true)?更新发起节点状态？thk
      f: 创建新的下一步节点
