A syntax from imports new package namespace from the external module assembly.
imports [namespace] from [module.dll]
imports "script.R"if the module file is missing file extension name, then the file extension name dll will be used as default.
00 Remarks
imports关键词的功能除了可以导入dll模块之中的包模块以外，也可以导入R脚本。 导入R脚本的功能和source函数保持一致，但是存在一些行为上的区别：
source函数要求脚本文件必须是一个正确的绝对路径或者相对路径imports关键词则无此要求，因为imports关键词会自动进行脚本文件的搜索操作为了兼容javascript的调用，在导入模块成功的时候还会在全局环境中生成模块的变量
