Overview

## Base

Base class for ‘chef generate` subcommands. Contains basic behaviors for setting up the generator context, detecting git, and launching a chef converge.

The behavior of the generators is largely delegated to a chef cookbook. The default implementation is the ‘code_generator` cookbook in chef-cli/skeletons/code_generator.
