* Call

* This method will check the HTTP request to see if it is a CSS file. If
* so, it will attempt to find a corresponding LESS file. If one is found,
* it will compile the file to CSS and serve it, optionally saving the CSS
* to a filesystem cache. The request will end at this point.
*
* If the request is not for a CSS file, or if the corresponding LESS file
* is not found, this middleware will pass the request on.
