Documentation suggestion - would be nice to indicate this requires contentstack.utils as a dependency #37

We're in the process of implementing this/using this tool, and I didn't realize we'd also have to include contentstack.utils nuget package in our web app. I don't see anywhere on Github (nor ContentStack) docs indicating this. This satisfies the Contentstack.Utils namespace usages the generator emits.

I see another using namespace - Contentstack.Core.Models - and I have no idea where this is meant to come from. I assume another nuget package, like contentstack.csharp ?
