    This is a pre-request script for Postman collections, folders, or requests that imports
    packages from npm after bundling them through [Browserify-CDN](https://wzrd.in/).
    
    ## Usage
    
    In global, collection, or environment variables, define a variable named `dependencies`
    that lists packages to import in the form `<package-name>@<version>`.  To include
    multiple packages, separate the package specs with commas
    (e.g., `async@latest,debug@4.1.1`).
