Remove Line Reader from Index

[SpiderMath]

In the index.js of the project Line 4, you imported the line-reader package. But I've checked through out the file, you did not use that, in any part of the code. So I would suggest that, you remove the import for it in Index.js (I know you required it in other files, so I don't think you should uninstall the whole package)
