Piecewise linear function manipulation utilities

This crate provides utilities to manipulate continuous
piecewise linear functions.
These are functions whose graph is made up of straight-line sections:

It uses geo for geometric primitives and types.

Usage example

let f = PiecewiseLinearFunction::try_from(vec![(0., 0.), (1., 1.), (2., 1.5)]).unwrap();
assert_eq!(f.y_at_x(1.25), Some(1.125));

Features

• Efficient iterator over inflection points of n functions
• Shrink and expand function domain
• Sum
• Max
• Numerical integration
• Negation

Various convenience features are also implemented. See
the documentation
for more details. Pull requests for other features are very welcome!

Other things to be done

• Improve CI with clippy and fmt
• Benchmarks
• Add links in rustdoc
• More tests
