格网分析：矩形、六边形

此接口可以完成数据的后台网格聚合统计，用于网格密度展示或热力图。如果不传入lngWidth和latWidth参数，后台把每一个瓦片（一般是256256 像素的瓦片）分成88=64个小网格，统计落在每个网格内数据的数量，并且可以指定一个数据集属性（数字或字符串类型，后台会把字符串自动转成数字）做为加权值。对于大数据量（比如一次查询的数据量在五万以上），第一次查询会比较慢，推荐传入cache参数，使后台把查询到的数据自动归属到相关瓦片，并缓存起来。如果下次查询的范围没有超出已缓存的瓦片数据，后台会把范围内的瓦片网格数据自动拼装起来返给前端。但这样做的话下次访问就不是实时运算了，如果需要重新运算，需要调用另一个接口清除缓存的数据
