viexpl - 临时测试版

针对一个数据视图（数据子集，由若干行列构成），（讨论输入视图到底是什么，是否包含聚合信息），使用预设的固定类型的洞察检测算子进行检测。最终生成视图对应在每个洞察类型上的显著性评分，和该洞察的一些具体的信息（如异常值、周期、和全局分布差异大的子分部等）

接口

传入参数

interface IStartSerive {
    dataSource: IRowp[];
    fields: IColumnp[];
    check_list: string[];（需要计算的洞察类型列表，默认为全部）
    breakdown: string[];（默认为区分度最大维度）
    aggrType: string;（默认为mean）
    subspaces: Array<IRowp[]>;（默认为最大子空间）
    rangeN: int;（默认为5）
}

返回

interface IStartReturns {
    success: boolean;
    data: Array<insightTypes: （insightTypes为洞察类型，与check_list输入对应）
        {
            'score':score,
            'para':
            {
                para（画图相关参数）
                'explain':string;(描述文本)
            }
        }>
}
