//! Dive planning library

//! ```
//! use capra::modes::open_circuit::OpenCircuitParams;
//! use capra_core::{common, deco};
//! use time::Duration;
//! use capra::modes::OpenCircuit;
//! use capra::DivePlan;

//! use capra_core::deco::zhl16::variant::Variant::B;
//! let air = common::Gas::new(21, 0, 79).unwrap();
//!
//! // Make a new ZHL16 decompression model
//! let zhl16 = deco::zhl16::ZHL16::new(
//!     deco::Tissue::default(),
//!     TissueConstants::new_by_variant(B),
//!     50,
//!     70,
//! );
//!
//! // Make a dive segment
//! let dive_segment = common::DiveSegment::new(

//!     45,
//!     45,
//!     Duration::minutes(60),

//! .unwrap();
//!
//! let deco_gases = vec![(air, None)];
