/**
* A utility function to rebase a (partial) URL based on the live_site and base_url of the application configuration
* in the provided container. You can override the base_url of the application through the $baseUrl parameter.
*
* It's simpler to explain with a short example. Let's consider an application with
* live_site = 'http://www.example.com' and base_url='/administrator/index.php?option=com_foobar&baz=1'.
* Using Uri::rebase('?view=report&item=export', $container) will result to the following absolute URL:
* http://www.example.com/administrator/index.php?baz=1&item=export&option=com_foobar&view=report
* Using Uri::rebase('?option=com_whatever', $container) will result to the following absolute URL:
* http://www.example.com/administrator/index.php?baz=1&option=com_whatever
* Therefore by manipulating the base_url in the application's configuration you can have an application which runs
* inside another application (no matter if the other application is based on Awf or not). The "only" thing you will
* have to do is specialise your Application object to act as a bridge to the parent application.
