Gulp Babel External Helpers
A gulp plugin that replaces gulp-babel, it does the same thing except it also tracks what helpers are used and exports them as a seperate module and includes that require in each file that needs them. Allowing you use external helpers without polluting the global context.
gulp//------------V (where this file would be if it was in src )// will end up with a ./lib/helpers.js file containing the bable helpers
babelConfigjust a normal babel options object
imaginaryLocationInSrc- This is the location of the helpers file if it were to exist in your source directories, this tells the plugin how to build the
require('./helpers')import for each file and so it can be added into the file stream usefully.
