Overview
This class is only used directly from the Chef::CookbookLoader and from chef-fs, so it only affects legacy-mode chef-client runs and knife. It is not used by server or zolo/zero modes.
This seems to be mostly a glorified factory method for creating CookbookVersion objects now, with creating Metadata objects bolted onto the side? It used to be also responsible for the merging of multiple objects when creating shadowed/merged cookbook versions from multiple sources. It also handles Chefignore files.
