/**
 * Base class to create strongly typed Svelte components.
 * This only exists for typing purposes and should be used in `.d.ts` files.
 *
 * ### Example:
 *
 * You have component library on npm called `component-library`, from which
 * you export a component called `MyComponent`. For Svelte+TypeScript users,
 * you want to provide typings. Therefore you create a `index.d.ts`:
 * ```ts
 * import { SvelteComponentTyped } from "svelte";
 * export class MyComponent extends SvelteComponentTyped<{foo: string}> {}
 * ```
 * Typing this makes it possible for IDEs like VS Code with the Svelte extension
 * to provide intellisense and to use the component like this in a Svelte file
 * with TypeScript:
 * ```svelte
 * <script lang="ts">
 * 	import { MyComponent } from "component-library";
 * </script>
 * <MyComponent foo={'bar'} />
 * ```
 *
 * #### Why not make this part of `SvelteComponent(Dev)`?
 * Because
 * ```ts
 * class ASubclassOfSvelteComponent extends SvelteComponent<{foo: string}> {}
 * const component: typeof SvelteComponent = ASubclassOfSvelteComponent;
 * ```
 * will throw a type error, so we need to separate the more strictly typed class.
