// The following property can be used to seed Global Context with predefined
    // values. This allows extra node modules to be made available with the
    // Function node.
    // For example,
    //    functionGlobalContext: { os:require('os') }
    // can be accessed in a function block as:
    //    global.get("os")
    functionGlobalContext: {
        // os:require('os'),
         jfive:require("johnny-five"),
         j5board:require("johnny-five").Board({repl:false})
    },
    // `global.keys()` returns a list of all properties set in global context.
    // This allows them to be displayed in the Context Sidebar within the editor.
    // In some circumstances it is not desirable to expose them to the editor. The
    // following property can be used to hide any property set in `functionGlobalContext`
    // from being list by `global.keys()`.
