[SR-Users] app_python not able to import from Router

Hello again,

It seems as though the python module has been changed, but the example
python script wasn't changed to reflect the changes. From looking at
the source code it seems to me that the function hierarchy had been
changed (or created, rather). So if the following line is changed
from:
"from Router import LM_ERR"
to
"from Router.Logger import LM_ERR"
kamailio (and the embedded python code) will run without problems.

In lieu of better documentation, perhaps the sample code should be
changed or altogether removed.

Regards,
Örn
