* Sets the current Puli directory.

* The current Puli directory is directory of the currently loaded Twig
* template. For example, if the template "/webmozart/puli/views/index.html"
* is being loaded, then "/webmozart/puli/views" is the current directory.
* If asset inputs are given as relative path, the relative paths are
* searched for in this directory of the Puli repository.
*
* The asset name is generated when this method is called. Once generated,
* the name cannot be changed anymore. Hence this method can be called only
* once.
*
* @param string $currentDir The current Puli directory.
*
* @throws RuntimeException If the method was already called before.
