How to create a new extension for Cartalyst Platform?

Hi, I installed Cartalyst Platform 4.0 and I am trying to play around with it so I can understand it since the is not a whole lots of lessons out there.

I simply copied the Access Extension located on \extensions\platform\access into and \extensions\crm\access and then I renamed it to "accounts" (i.e.\extensions\crm\accounts)

Then I changed all the name spaces to the new path.

But every time I open my app I get this error Class 'crm\Accounts\Providers\AccountsServiceProvider' not found

I don't know why am I getting this error I do have AccountsServiceProvider.php file with the AccountsServiceProvider class name located on \extensions\crm\accounts\Providers

I am not sure is it because I created another folder next to the platform? I am just trying to keep my extensions separate from the extensions that comes with the Platform.

What do I need to do to fix this issue?

Here is my AccountsServiucePrivider class

<?php
namespace crm\Accounts\Providers;

use Illuminate\Support\Facades;
use Platform\Access\Redirector;
use Platform\Access\UrlGenerator;
use Cartalyst\Support\ServiceProvider;

class AccountsServiceProvider extends ServiceProvider
{
    /**
     * {@inheritDoc}
     */
    public function boot()
    {
        // Load the filters
        require __DIR__.'/../filters.php';

        // Overrides the Sentinel models
        $this->overrideSentinelModels();
    }

    /**
     * {@inheritDoc}
     */
    public function register()
    {
        $this->prepareResources();

        $this->registerMiddleware();

        $this->setAdminUri();
    }

    /**
     * Prepare the package resources.
     *
     * @return void
     */
    protected function prepareResources()
    {
        $config = realpath(__DIR__.'/../../config/config.php');

        $this->mergeConfigFrom($config, 'crm-accounts');

        $this->publishes([
            $config => config_path('crm-accounts.php'),
        ], 'config');
    }

    /**
     * Registers the permissions middleware.
     *
     * @return void
     */
    protected function registerMiddleware()
    {
        $this->app['router']->middleware('permissions', 'Platform\Access\Middleware\Permissions');
    }

    /**
     * Sets the admin uri on the url generator.
     *
     * @return void
     */
    protected function setAdminUri()
    {
        $this->app['url']->setAdminUri(admin_uri());
    }

    /**
     * Overrides the Sentinel models.
     *
     * @return void
     */
    protected function overrideSentinelModels()
    {
        // Get the roles and users models
        $rolesModel = get_class($this->app['Platform\Roles\Models\Role']);
        $usersModel = get_class($this->app['Platform\Users\Models\User']);

        // Set our models within Sentinel
        $this->app['sentinel.roles']->setModel($rolesModel);
        $this->app['sentinel.users']->setModel($usersModel);
        $this->app['sentinel.persistence']->setUsersModel($usersModel);

        // Override the users model on the roles model
        $rolesModel::setUsersModel($usersModel);

        // Override the roles model on the users model
        $usersModel::setRolesModel($rolesModel);
    }
}
