//! Grid Engine is a flexible and efficient library for managing 2D grid-based layouts.
//!
//! This crate provides functionality for:
//! - Managing items in a 2D grid with automatic collision handling
//! - Dynamic vertical expansion of the grid
//! - Event system for tracking grid changes
//! - Strong type safety and error handling
//!
//! # Example
//!
//! ```rust
//! use grid_engine::grid_engine::GridEngine;
//! # use std::error::Error;
//!
//! # fn main() -> Result<(), Box<dyn Error>> {
//! // Create a new 10x12 grid
//! let mut grid = GridEngine::new(10, 12);
//!
//! // Add items (automatic collision handling)
//! grid.add_item("box1".to_string(), 0, 0, 2, 2)?;
//!
//! // Move items
//! grid.move_item("box1", 2, 2)?;
//!
//! # Ok(())
//! # }
//! ```
//!
//! See the `examples` directory for more usage examples.
