[Flask] errors w/ flask deployment with emperor

[tigernassau]

okay, we took another try at getting flask to deploy using emperor
server: debian 8, using python3

server runs bottle apps fine

here is the config we tried - get error:  "curse the vassal... 
/etc/uwsgi/vassals/testapp.ini
couldn't find any more details on what is wrong

btw had to run uwsgi emperor as sudo since the systemd service failed 
with log file permission error
