About the Config class

The Config() class has three methods to return the builders:

Method	Description
`builder()`	Returns a naked builder for `Config` objects.
`parseYaml(String input)`	Parses the YAML content and returns a `Config.Builder`
`parseJson(String input)`	Parses the JSON content and returns a `Config.Builder`

The following example illustrates how to use the Config.builder() method:

Config cfg = Config.parseYaml(STD_CONFIG)
  .basePath(baseUrl)
  .build();

Config cfg = Config.builder()
  .basePath(baseUrl)
  .build();
}

The configuration object utilizes builders to construct immutable objects. The Config class parses the external configuration to produce a runtime Config.Builder object that allows you to modify the configuration. After modifying the configuration, use the builder's build() method to construct the new immutable config object.
