+//! Coordinate vectors for positional data
+//!
+//! These types differ from the vector types implemented in `core::vec` because
+//! they describe coordinates in geometric space and not a magnitude and a
+//! direction. All positional data throughout the library uses these point
+//! types, which allows for a clear, self-documenting API.
