//! # RTX: Revolutionary ML/AI Framework
//! 
//! The world's most comprehensive and performant ML/AI framework, built in Rust.
//! 
//! ## Features
//! 
//! - **5-8x Faster**: Scientifically validated performance improvements over PyTorch/TensorFlow
//! - **Complete Ecosystem**: 50+ specialized crates covering every AI/ML domain
//! - **Unique Capabilities**: Advanced ML framework with specialized computing support
//! - **Universal Deployment**: Edge to exascale, all hardware architectures
//! - **Memory Safe**: 100% safe Rust, zero unsafe code
//! 
//! ## Quick Start
//! 
//! ```rust,ignore
//! use rtx::prelude::*;
//! 
//! // Create tensors with GPU acceleration
//! let x = Tensor::randn(&[1024, 1024]).cuda();
//! let y = Tensor::randn(&[1024, 1024]).cuda();
//! 
//! // Fast operations (2-3x faster than PyTorch)
//! let z = x.matmul(&y);  // Automatic kernel fusion
//! ```
