Dependency Counts

Methodology: Dependency Counts.

For dependency counts, we start by looking at the dependencies for the meta-framework package directly. For example, how many production, development and overall dependencies does `Nuxt` have? We then look at dependencies for the starter projects specifically. Looking at a project's dependencies is more realistic (like the `starter-*` projects) as meta-frameworks rarely just include the meta-framework package alone. It is also important to look at direct dependencies.
