     * Currently, all user configuration is stored in a JSON file (bloom.json), in the user's project directory.
     *
     * The JSON config file should define debugging environment objects. A debugging environment object is just
     * a user defined JSON object that holds parameters relating to a specific debugging environment (like the
     * name of the DebugTool, Target configuration and any debug server config). Because a config file
     * can define multiple debugging environments, each object should be assigned a key in the config file. We use this
     * key to allow users to select different debugging environments between debugging sessions.
     *
     * On application startup, we extract the config from this JSON file and generate an ApplicationConfig object.
     * See Application::extractConfig() for more on this.
     *
     * Some config parameters are specific to certain entities within Bloom, but have no significance across the
     * rest of the application. For example, AVR8 targets require 'physicalInterface' and 'configVariant' parameters.
     * These are used to configure the AVR8 target, but have no significance across the rest of the application.
     * This is why some configuration structs (like TargetConfig) include a QJsonObject member, typically named jsonObject.
     * When instances of these structs are passed to the appropriate entities, any configuration required by those
     * entities is extracted from the jsonObject member. This means we don't have to worry about any entity specific
     * config parameters at the application level. We can simply extract what we need at an entity level and the rest
     * of the application can remain oblivious. For an example on extracting entity specific config, see AVR8::configure().
