Merge remote-tracking branch 'erikiv/master'
Fixed that classes in models/*.rb can't be deserialized without 'include Bio::BaseSpace' (e.g., NameError: uninitialized constant AppSessionResponse)
Finished the Cookbook section (not well tested though) and add cosmetics on white spaces at the beggining of lines of the code blocks
Merge branch 'master' of https://github.com/ktym/basespace-ruby-sdk into ktym-master
