/**
 * Directories are services that contain a
 * [list]{@link DirectoryModel#list}
 * of the names of the
 * [BehaviorSubjects]{@link https://www.learnrxjs.io/learn-rxjs/subjects/behaviorsubject}
 * contained in the
 * [dir]{@link DirectoryModel#dir}
 * object, a 'dir' object that is a Directory of BehaviorSubjects, and a
 * [backupObjs]{@link DirectoryModel#backupObjs}
 * Directory of JSON objects. A Directory is a specific term for this framework
 * where instead of using an array of objects, we use an object where the top-level
 * keys are the name of an object, and the value is the object itself. Most
 * Angular frameworks and tutorials recomend using arrays of objects for their
 * templating, and then use the filter or sort methods to control the display or
 * selection of a particular object within the array of objects. But for massive
 * arrays, the filter method can be incredibly slow. The UiDirectory contains
 * all of the JSON objects that serve as instructions for components used to
 * build themselves. These UI objects are further organized into 'groups' such
 * as 'buttons', 'panels, and 'pages'. A component (such as a button) that has
 * received a name, can then search the respective group (such as 'buttons') to
 * find its own name and assign those instructions to itself.
