     * "src/main/resources/htmlFilesInput/" folder, so make sure to put the html
     * file to convert into that folder. If this input folder doesn't exist on a
     * project using our library jsgenerator then it will be created. The generated
     * Js files will be located in "src/main/resources/jsFilesOutput/" folder.
     * Concerning this library, by default, the input folder exists but the output
     * folder don't. When a project will use jsgenerator as dependency, an input
     * folder will be created as soon as possible its classpath will contain
     * jsgenerator.</b>
