* 通用分页列表数据集获取方法
*
* 可以通过url参数传递where条件,例如: index.html?name=asdfasdfasdfddds
* 可以通过url空值排序字段和方式,例如: index.html?_field=id&_order=asc
* 可以通过url参数r指定每页数据条数,例如: index.html?r=5
*
* @param sting|Model $model 模型名或模型实例
* @param array $where where查询条件(优先级: $where>$_REQUEST>模型设定)
* @param array|string $order 排序条件,传入null时使用sql默认排序或模型属性(优先级最高);
* 请求参数中如果指定了_order和_field则据此排序(优先级第二);
* 否则使用$order参数(如果$order参数,且模型也没有设定过order,则取主键降序);
*
* @param boolean $field 单表模型用不到该参数,要用在多表join时为field()方法指定参数
* @author 朱亚杰 <*****@*****.**>

* @return array|false
* 返回数据集
