                Please write an AIDL program to generate a castle

Sure! Let's start by defining the basic structure of the castle. For simplicity, let's focus on the main sections of the castle which include a central keep (main tower), surrounding walls, and corner towers.

### Step 1: Define the Structures and Their Hierarchical Relationships

We'll start by thinking about the main components of the castle:
1. **Keep**: The main tower in the center.
2. **Walls**: Surrounding the keep.
3. **Corner Towers**: Located at the corners of the walls.

### Step 2: Add Compositional Constraints to Position and Size the Structures

We will need to define constraints to position and size the structures relative to each other.

### Step 3: Define Geometry for Each Structure

We'll create the shapes for each part of the castle:
- **Keep**: A simple rectangle to represent the tower.
- **Walls**: Lines to form a square or rectangular boundary.
- **Corner Towers**: Circles or rounded rectangles at the corners of the walls.

### Step 4: Add Local Constraints for Each Structure

We'll ensure that each part maintains its shape and position as per our initial design.

Here is the AIDL program step by step to generate the castle:

```python
from AIDL import *

def castle(
    keep_width: float = 5 * inches,
    keep_height: float = 10 * inches,
    wall_length: float = 20 * inches,
    wall_height: float = 5 * inches,
    tower_radius: float = 2 * inches
):
    """
    Model a simple castle with a central keep, surrounding walls, and corner towers.
    """
    castle = Solid()
    keep = Solid(shift=(0, 0))
    walls = Solid()
    towers = [Solid(shift=(wall_length/2, wall_length/2)),
              Solid(shift=(-wall_length/2, wall_length/2)),
              Solid(shift=(-wall_length/2, -wall_length/2)),
              Solid(shift=(wall_length/2, -wall_length/2))]

    castle.keep = keep
    castle.walls = walls
    castle.towers = {f"tower_{i}": tower for i, tower in enumerate(towers)}
    
    # Define the keep geometry
    keep.body = Rectangle((0,0), keep_width, keep_height)

    # Define the wall geometry
    walls.top = Line((-wall_length/2, wall_height/2), (wall_length/2, wall_height/2))
    walls.bottom = Line((-wall_length/2, -wall_height/2), (wall_length/2, -wall_height/2))
    walls.left = Line((-wall_length/2, -wall_height/2), (-wall_length/2, wall_height/2))
    walls.right = Line((wall_length/2, -wall_height/2), (wall_length/2, wall_height/2))

    # Define the corner tower geometry
    for tower in towers:
        tower.body = Circle((0,0), tower_radius)

    # Compositional Constraints for keeping the walls and towers aligned
    # Ensure the walls form a closed boundary around the keep
    walls.AddConstraint(walls.top.length == wall_length)
    walls.AddConstraint(walls.bottom.length == wall_length)
    walls.AddConstraint(walls.left.length == wall_height)
    walls.AddConstraint(walls.right.length == wall_height)
    walls.AddConstraint(Coincident(walls.top.end, walls.right.end))
    walls.AddConstraint(Coincident(walls.bottom.end, walls.right.start))
    walls.AddConstraint(Coincident(walls.bottom.start, walls.left.start))
    walls.AddConstraint(Coincident(walls.top.start, walls.left.end))
    
    # Towers are at the corners of the walls
    for idx, tower in enumerate(towers):

        if idx == 0:
            castle.AddConstraint(Coincident(tower.body.center, walls.top.end))
        elif idx == 1:
            castle.AddConstraint(Coincident(tower.body.center, walls.top.start))
        elif idx == 2:
            castle.AddConstraint(Coincident(tower.body.center, walls.bottom.start))
        elif idx == 3:
            castle.AddConstraint(Coincident(tower.body.center, walls.bottom.end))

    # Add a hole for the entrance in the front wall (optional)
    front_entrance = Hole()
    front_entrance.door = Rectangle((0, -wall_height/2), keep_width/2, wall_height/3)
    walls.front_entrance = front_entrance
    walls.AddConstraint(Coincident(front_entrance.door.left.start, walls.bottom.midpoint))

    return castle

with AIDL_2D:
    model = castle()
print(model.Solve())
model.Render()
```

### Explanation:
1. **castle Structure**: The main structure that holds everything.
2. **keep**: A simple rectangle representing the central tower.
3. **walls**: Lines forming a square/rectangle surrounding the keep.
4. **towers**: Circles at each corner of the wall.
5. **front_entrance**: An optional door hole to represent the entrance to the castle.

### Constraints:
- The walls form a closed boundary.
- Towers are placed at the corners of the walls.
- The keep is centrally positioned within the walls.
- Optional: Front entrance is centered along the bottom wall.
