## Description

A ROS2 service client node that calls the `add_two_ints` service with two integers (2 and 3) and displays the result. This demonstrates synchronous service client usage with `spin_until_future_complete` in Python.

## Services

- **Service Client**: `/add_two_ints`
  - **Type**: `example_interfaces/srv/AddTwoInts`
  - **Description**: Calls the add_two_ints service to add two numbers

## Example Usage

```bash
# Run the client (requires add_two_ints_server to be running)
ros2 run demo_nodes_py add_two_ints_client
```

The client will output:
```
service not available, waiting again...  # (if server not ready)
[INFO] [add_two_ints_client]: Result of add_two_ints: 5
```

Complete example:
```bash
# Terminal 1: Run the server
ros2 run demo_nodes_py add_two_ints_server

# Terminal 2: Run the client
ros2 run demo_nodes_py add_two_ints_client
```
