Overview

Note:

This is a class with a greater “reek” than I would like. However, it is parsing JSON and loading that into ruby; Its complicated. So I’m willing to accept and assume responsibility for this code “reek”.

Responsible for building a class based on the given JSON document.

Note the following structure:

Commands that are called against the builder are Hash keys that start with ‘#’. Keywords are command parameters that do not start with ‘#’.

Examples:

```json
{ "#command_name": { "keyword_param_one": "param_value", "#nested_command_name": { "nested_keyword_param": "nested_param_value"} } }
```
