function sutureSpineObj(spineObjs...)

the order of the elements could be control by the global var 'rule' by the order to make many spine model together

function amputateSpineObj(spineObj, byParts)

fliter a spine model to a spine model only have byParts' prefix elements need to do this many time to fliter all the prefix

肢解 sutureSpineObj 将spine对象过滤为只有byParts字符串开头的spine对象 过滤多个则需要多次拆分

缝合 amputateSpineObj 需要lodash环境 lodash needed 排序需要修改rule 将多个spine对象按排序规则组合到一起。
