ENV for the URL :: not working?

When I try to call Beaneater.new with teh env variable set I get this:

> ArgumentError: wrong number of arguments (given 0, expected 1)
/path/vendor/bundle/ruby/2.5.0/gems/beaneater-1.0.0/lib/beaneater.rb:24:in `initialize'

I assume that's not intended. When I adjusted both of these:

> /path/vendor/bundle/ruby/2.5.0/gems/beaneater-1.0.0/lib/beaneater/connection.rb: def initialize(address)
/path/vendor/bundle/ruby/2.5.0/gems/beaneater-1.0.0/lib/beaneater.rb: def initialize(address)

To be address = nil it works. However, I don't know how we want to solve that problem. At the moment I'm solving it like this:

> Beaneater.new(ENV['BEANSTALKD_URL'])

Which I doubt is the intended behavior. I'm assuming no one uses this ENV at this point as it seems to not work.

Inspect lib/beaneater.rb and lib/beaneater/connection.rb, focusing on the initialize methods and how BEANSTALKD_URL is used when no address is passed. Reproduce the environment-based call and verify that Beaneater.new uses the environment URL while an explicitly supplied address still works.
