BUG subTemplates should be an array
See `SSViewer::templates()`and `SSViewer::setTemplateFile()` Methods assume this variable should be an array. If you call `setTemplateFile()` directly prior / instead of any `setTemplate` call then a PHP warning is generated `[Warning] array_merge(): Expected parameter 2 to be an array, null given`
