节点排序：inject+function+switch+functionX2+debug

inject节点 属性 msg.age = 随机数字

function节点 函数 msg.age = 6 

                            return msg;

switch节点 属性msg.age

                 在之间 数字0 与 数字18

                 在之间 数字19 与 数字60

function节点 函数 msg.age = '未成年'

                            return msg;

function节点 函数 msg.age = '成年'

                           return msg;

debug节点 输出 msg.age
