 * @description
 * The VendurePlugin decorator is a means of configuring and/or extending the functionality of the Vendure server. A Vendure plugin is
 * a [Nestjs Module](https://docs.nestjs.com/modules), with optional additional metadata defining things like extensions to the GraphQL API, custom
 * configuration or new database entities.
 *
 * As well as configuring the app, a plugin may also extend the GraphQL schema by extending existing types or adding
 * entirely new types. Database entities and resolvers can also be defined to handle the extended GraphQL types.
 *
 * @example
 * ```ts
 * import { Controller, Get } from '\@nestjs/common';
 * import { Ctx, PluginCommonModule, ProductService, RequestContext, VendurePlugin } from '\@vendure/core';
 *
 * \@Controller('products')
 * export class ProductsController {
 *     constructor(private productService: ProductService) {}
 *
 *     \@Get()
 *     findAll(\@Ctx() ctx: RequestContext) {
 *         return this.productService.findAll(ctx);
 *     }
 * }
 *
 *
 * //A simple plugin which adds a REST endpoint for querying products.

 *     imports: [PluginCommonModule],
 *     controllers: [ProductsController],
 * })
 * export class RestPlugin {}
