//! rUv Neural Graph -- Brain connectivity graph construction from neural signals.
//!
//! This crate builds brain connectivity graphs from multi-channel neural time series
//! data, provides graph-theoretic metrics, spectral analysis, and temporal dynamics
//! tracking for brain topology research.
//!
//! # Modules
//!
//! - [`atlas`] -- Brain atlas definitions (Desikan-Killiany 68 regions)
//! - [`constructor`] -- Graph construction from connectivity matrices and time series
//! - [`petgraph_bridge`] -- Convert between `BrainGraph` and petgraph types
//! - [`metrics`] -- Graph-theoretic metrics (efficiency, clustering, centrality)
//! - [`spectral`] -- Spectral graph properties (Laplacian, Fiedler value)
//! - [`dynamics`] -- Temporal graph dynamics and topology tracking
