php-ews folders do not match php-ews code at all - exchange-server-2010

Question

Installed php-ews using composer:
{
"minimum-stability": "dev",
"prefer-stable": true,
"require":
{
"php-ews/php-ews": "dev-master"
}
}
The installation passed fine.
Made this simple request in my project code:
require_once 'composer/vendor/autoload.php';
use \php-ews\php-ews\src\Client;
$host = 'my.server.co.il';
$username = 'user#server.co.il';
$password = 'myPass';
$version = Client::VERSION_2010;
$client = new Client($host, $username, $password, $version);
But the PHP doesn't accept hyphens (-) in its use command path,
I got the error:
PHP Parse error: syntax error, unexpected '-', expecting ',' or ';' in /var/www/html
Then I noticed, the paths of the use phrases in all the code files of the php-ews project, do not match the project files that where installed using the composer at all. For example, in the create.php file there are use phrases:
use \jamesiarmes\PhpEws\Client;
use \jamesiarmes\PhpEws\Request\CreateItemType;
use \jamesiarmes\PhpEws\ArrayType\NonEmptyArrayOfAllItemsType;
use \jamesiarmes\PhpEws\ArrayType\NonEmptyArrayOfAttendeesType;
use \jamesiarmes\PhpEws\Enumeration\BodyTypeType;
use \jamesiarmes\PhpEws\Enumeration\CalendarItemCreateOrDeleteOperationType;
use \jamesiarmes\PhpEws\Enumeration\ResponseClassType;
use \jamesiarmes\PhpEws\Enumeration\RoutingType;
The above paths do not even exist in the project at all....
The project files and folders that the composer installed, they do not match the code use and require phrases inside of them.
Did I make the wrong installation?
is there other way to use the composer.json file so I can install the project right, without hyphens (php-ews) in the directories?

Answer 1

installation seems correct.
require != use
use is a namespace, this on is defined in the Client.php, which is autoloaded.
client.php line 6:
namespace jamesiarmes\PhpEws;
