Subject: [PATCH 1/3] Update babel to use preset-env

per https://babeljs.io/docs/en/env/ -- updated from preset-es2015 to preset-env. Also updated @babel-cli and @babel-core versions
to be compatible. Updated shell in Makefile to set path variable, otherwise I was getting missing babel errors as I don't have
babel installed globally.
