the class RenderAssetsDirective method renderAssets.

/**
 * Renders queued asset links as HTML. If in dev mode, the rendered output will be a sequence of plain links to the
 * asset resources. Else, the queued assets will be compiled into a minified form, and the rendered output will be a
 * single link to the result.
 * <p/>
 * Either way, assets will be ordered according to their dependencies, defaulting to the order in which they were
 * enqueued. (That is, in dev mode the links appear in that order, and in production mode the assets are concatenated
 * in that order before they are minified.)
 * <p/>
 * This method pulls asset nodes from the named environment variable. Executing the method clears the queue.
 *
 * @param assetType           defines the type of asset (.js or .css)
 * @param requestVariableName the name of the request variable that uncompiled assets have been stored in by calls to
 *                            a subclass of {@link AssetDirective}
 * @param environment         freemarker execution environment
 * @throws TemplateException
 * @throws IOException
