The View class allows you to load views, assets such as javascript and style sheet files, and specify other various options for view files.
includeJavascript

// <script type="text/javascript">head.js("http://www.example.com/externals/file.js");</script>
view::includeJavascript('externals/file.js');
// // the following code will produce this output right above the </body> tag of the page
// <script type="text/javascript">head(function(){alert("hey!");});</script>
view::includeJavascript('alert("hey");', 'footer');includeStylesheet
Assign style sheet file to be included when page is displayed.
// the following code will produce this output in the <head> section of the page
