This library is the Rust reference implementation for SAC13 and maintains data types and functions
to convert, among others, from and to

  - [Gregorian Calendar dates]https://docs.rs/sac13/latest/sac13/struct.GregorianDate.html
  - [JulianDays]https://docs.rs/sac13/latest/sac13/day_counts/struct.JulianDay.html
  - [UnixDays]https://docs.rs/sac13/latest/sac13/day_counts/struct.UnixDay.html (days since 1970-01-01)

## Quick start
```rust
use sac13::prelude::*;

pub fn main() {
  // TODO: add code :-)
}
```

## Breaking Changes
Note, this library is pretty new so there will be a lot of breaking changes at least until we hit `0.1`. The plan is to keep it relatively stable after that with the help of semver-checks.
