ores dev_server requires pylru

#110 appears to have regressed.

I did a fresh pip install ores and then ores dev_server and it tells me that:

That's because of the way the dev server is configured. If you set it to use no cache, then it won't complain.

I'm not sure how to do that...maybe the documentation just needs updating? Currently the steps listed at https://github.com/wiki-ai/ores#installation don't work.

The problem I had running ores dev_server was:

Traceback (most recent call last):
File "/home/jonas/projects/sandbox/ores-test/3.4/bin/ores", line 11, in
sys.exit(main())
File "/home/jonas/projects/sandbox/ores-test/3.4/lib/python3.5/site-packages/ores/ores.py", line 54, in main

pip install yamlconf --upgrade
and then try again.

Oh! Actually, that's fine. The real problem is that there's no config provided. That error should be better. Try ./utility dev_server -h and see the --config option
