This is probably a stupid question, but I'm new to Ruby on Rails and I could use a little guidance. I want to have a helper/utility class that performs a group of network operations and returns results. Where do I put that class and how do I use it.

I've created network_helper.rb in my app/modulename/helpers directory. In my controller when I try to do 

  myNetworkHelper = ModuleName::NetworkHelper.new
  results = myNetworkHelper.getResults

I get an error 

 undefined method `new' for MyModule::NetworkHelper:Module

I'm sure this is just a misunderstanding of how ruby on rails works. Can I get some clarification?

Would it be better to make this a class instead of a module and put it in libs? And can I add subfolders in libs and have them automatically loaded?
