/**
 * A [[CMS]] is the core object of any content management system.
 *
 * The responsibility of the [[CMS]] keeps track of two broad types of objects:
 *
 * - [[Plugin|Plugins]] which extend or change the behaviour of the content management system..
 * - [[api|APIs]] which allow the CMS to integrate with third party services.
 * - [[EventBus|events]] which provide a way to communicate information about events happening
 *   between decoupled parts of the CMS.
 *
 * The name [[CMS]] is a bit misleading. This object knows nothing of the user
 * interface or the data storage layer. The purpose of a [[CMS]] instance is to
 * provide a common connection point for the various aspects of a content
 * management system. The [[CMS]] object effectively a vehicle for dependency injection.
 *
 * #### Creating a CMS
 *
 * ```ts
 * import { CMS } from "@tinacms/core"
 *
 * const cms = new CMS()
 * ```
 *
 * #### Extending the CMS
 *
 * The [[CMS]] class provides low-level interfaces for interacting with APIs and Plugins.
 * Creating a subclass is great way to facilitate these interactions:
 *
 * ```ts
 * import { CMS } from "@tinacms/core"
 *
 * class MyCMS extends CMS {
 *   get colors() {
 *     return this.plugins.findOrCreateMap("color")
 *   }
 * }
 *
 * const cms = new MyCMS()
 *
 * cms.colors.all()
 * ```
