Recently I had some urgency on one of my projects regarding separating memcached data by namespaces, so I've fixed memcached metastore and specced this behaviour.
Fixing badly written tests
Making memcached metastore backend be aware of namespace
speccing memcached namespace awareness of metastore and entitystore
Adding Gemfile.lock to .gitignore
minor update, reorganizing tests a little
Looks great. Thanks!
