* The Config class provides Nix runtime configurations.

* What is a Configuration?
* A collection of uniquely named Settings.
*
* What is a Setting?
* Each property that you can set in a configuration corresponds to a
* `Setting`. A setting records value and description of a property
* with a default and optional aliases.
*
* A valid configuration consists of settings that are registered to a
* `Config` object instance:
*
* Config config;
* Setting<std::string> systemSetting{&config, "x86_64-linux", "system", "the current system"};
*
* The above creates a `Config` object and registers a setting called "system"
* via the variable `systemSetting` with it. The setting defaults to the string
* "x86_64-linux", it's description is "the current system". All of the
* registered settings can then be accessed as shown below:
*
* std::map<std::string, Config::SettingInfo> settings;
* config.getSettings(settings);
* config["system"].description == "the current system"
* config["system"].value == "x86_64-linux"
