Example of workable collection usage

[j-dexx]

Hi, I thought it might be useful to add an example of how to use workable collections.

Basically just:

client = Workable::Client.new(api_key: 'api_key', subdomain: 'your_subdomain')
jobs = client.jobs
loop do
  jobs.each do |job|
    # Do something with the job
  end
  break unless jobs.next_page?
  jobs = jobs.fetch_next_page
end

Using loop because it's matz's preference

Would you like me to add it? If so where would you like it? Using yard in the workable collection class? Or in the readme?

Hi, sorry for slight delay, was pretty occupied lately; and sure - feel free to add this info, I think readme should be just fine (somewhere under usage) - as it's loaded by yard anyway. Thanks!

Sorry for the double commit reference - hadn't realised I changed the gitignore on the first one to ignore rubymine files.
