                Please write an AIDL program to generate a tree

Sure! Let's start by breaking down the components and relationships for a simple 2D tree. Here's the plan for the tree structure:

1. **Tree Trunk (Solid)**
   - A rectangle representing the trunk of the tree.
2. **Tree Branches (Solids)**
   - Multiple triangles to represent branches extending from the trunk.
3. **Leaves (Drawings)**
   - Circles to represent leaves for decorative details.

We'll start by defining these structures and then add geometric constraints to position them appropriately.

Let's get started:

```python
from AIDL import *

def tree(trunk_height: float = 5*inches, trunk_width: float = 1*inch, branch_height: float = 3*inches, branch_width: float = 6*inches):
    """
    Creates a simple 2D tree model with a trunk, branches, and leaves.
    """
    
    # Define the main structure for the tree
    tree = Solid()
    
    # Define the trunk
    trunk = Solid()
    tree.trunk = trunk
    
    # Define branches
    branches = [Solid() for _ in range(3)]
    for i, branch in enumerate(branches):
        tree.__setattr__(f'branch_{i}', branch)
    
    # Define leaves (as collection of circles for simplicity)
    leaves = Drawing()
    tree.leaves = leaves
    leaves.clusters = [Circle((i*0.8*inch - 1.6*inch, 2*trunk_height + branch_height*1.1), 0.5*inch) for i in range(-2, 3)]

    # Add constraints
    tree.AddConstraint(trunk.bb.bottom == 0) # Place trunk at bottom
    tree.AddConstraint(trunk.bb.left == -trunk_width / 2)
    tree.AddConstraint(trunk.bb.right == trunk_width / 2)
    tree.AddConstraint(trunk.bb.height == trunk_height)
    
    for i, branch in enumerate(branches):
        branch.AddConstraint(branch.bb.width == branch_width)
        branch.AddConstraint(branch.bb.height == branch_height)
        branch.AddConstraint(branch.bb.horizontal_center == 0)
        
        vertical_position = trunk_height + i * branch_height * 0.4 # Position branches stacked overlapping slightly
        branch.AddConstraint(branch.bb.vertical_center == vertical_position)
        
    # Define geometric primitives for the trunk
    trunk.body = Rectangle((0, trunk_height / 2), trunk_width, trunk_height)
    
    # Define geometric primitives for each branch
    for i, branch in enumerate(branches):
        height_offset = trunk_height + branch_height / 2 + i * branch_height * 0.4
        branch.body = Triangle((0, height_offset), branch_width, branch_height)
    
    # Leaf details (positioned above the last branch)
    leaf_y_position = trunk_height + len(branches) * branch_height * 0.4 + branch_height / 2
    for i, cluster in enumerate(leaves.clusters):
        leaves.__setattr__(f'leaf_{i}', cluster)
        tree.AddConstraint(cluster.center.u == (i - 2) * 0.8 * inch) # spread leaves horizontally
        tree.AddConstraint(cluster.center.v == leaf_y_position + 0.6 * inch) # place leaves

    return tree


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