Description

`interval_spec` public public data members

```
int factor;
```
Negative values denote special factor functions and get mapped to special_interval_factor. E.g. granularity=year_interval, factor=4 => every four years E.g. granularity=year_interval, factor=leapyear_interval_factor[-1] => every leap year
