| Register The Auto Loader
|--------------------------------------------------------------------------
|
| Composer provides a convenient, automatically generated class loader

| into the script here so that we do not have to worry about the
| loading of any our classes "manually". Feels great to relax.

| Turn On The Lights
|--------------------------------------------------------------------------

| We need to illuminate PHP development, so let's turn on the lights.
| This bootstraps the framework and gets it ready for use, then it
| will load up this application so that we can run it and send
| the responses back to the browser and delight these users.

| Capture The Request

| request class. We will then pass that to a Laravel application for
| processing and return the response we receive back from the app.

| the client's browser allowing them to enjoy the creative
| and wonderful application we have whipped up for them.
