/**
 * An application extends the service container
 * And exposes a set of methods for registering 'handlers'.
 * Handlers can be Lambda functions, http handlers, or GraphQL resolvers.
 *
 * These handlers are registered as part of the service container, which you can then
 * use to run locally, or deploy, depending on the methods called, and the decorators applied.
 *
 * For example, you could create an application with several lambdas, using the 'http' decorator.
 *
 * Under the hood, Yantra (code name), will utilise ais service discovery to bridge the gap between services,
 * and logic within this application.
 *
 * Because Yantra uses AWS CDK, you don't need to worry about permissions, these are handled in the most
 * secure way possible, because CDK will choose the most restrictive permissions possible, based on then
 * interlinking of your defined infrastructure. I.e, this will work out of the box, and will be optimally secure.
 *
 * app.run() will run the service locally
 * app.deploy() will run through the container for an infrastructure stack, and deploy it.
