#load_context ⇒ Object

Not using Lono::Template::Context because that works differently. That is used to load a context object that is passed to RenderMePretty’s context. So that we can load context for params files and erb templates.

In this case builder is actually the dsl context. We want to load variables and helpers into this builder context directly. This loads additional context. It looks very similar to Lono::Template::Context
