Major Description
Global scope is polluted by evaluated helium packages.
To reproduce this,
1. create packages that imports the most recent lodash (4.15.0+)
2. install that helium package.
3. open zeppelin-web using dev mode (PORT 9000)
4. manipulate some tables
Then, you will see `_.pluck` is not defined. (pluck is removed as of 4.0+)
