added simple cov file
Ignore vendor/bundle
Use newest evented_spec gem

We can't specify git repositories inside the
gemspec, so the include needs to be moved to
the Gemfile. We need the new evented_spec gem
to work with rspec 3.0.x
Update tests to use Rspec expect syntax
Add specific version of rspec

This is odd because on a new checkout
it installs 3.0.x, but CI only installed 2.14.x
Ignore the rspec output
Fix memory leak issue with lua code

Use the constant for the Lua code instead of
creating a new string on each method call.
Fix formatting, indentation
Use pending in place of xit, remove unused blocks
Bump version to 1.6, add description/summary

Bump the version for the memory leak fix.
Bump to 1.7 since 1.6 already exists on Rubygems
fixed bug: processing more than 1m messages at once caused a EM to hit its max timer limit bc it does not clean up its timers as fast as we can cancel them; this reduces the number of timers created by several orders of magnitude; also increased performance by freeing up some CPU
minor performance enhancements
WIP: fixed CPU/EM issue, now fighting an infinite loop caused by two concurrent consumers
removed pubsub in favor of polling bc it is simpler (and faster!)
updated README and added namespacing to headers
added ability to have multiple instances of worker_roulette that connect do different Redis servers
after due consideration, removed namespace from default headers since the tradesman has to know this ahead of time anywhere a message is received anyways
