Changes

Changed IConfigurator to return IConfigurator instead of void for the following interface methods:

• SetHelpProvider
• SetHelpProvider<T>
• AddExample

However, other methods like AddCommand narrow the configurator so the order of chaining methods does matter. Just to point that out. Chaining is optional obviously.

I saw the ICofiguratorOfT also returns void for SetDescription, and AddExample. However, it becomes a bigger challenge to change that because Configurator<T> implements both IUnsafeBranchConfigurator and IConfigurator<T> and both share the SetDescription and AddExample but one does not take in the generic type. Probably would need "unsafe configurator of T" or something?
