-In order to simplify referencing common paths the modules in our application may use, we use a RequireJS [configuration object](http://requirejs.org/docs/api.html#config), which is typically defined as a top-level script file. Configuration objects have a number of useful capabilities, the most useful being mode name-mapping.
