A simple library wrapping [sergi/go-diff](https://github.com/sergi/go-diff).
## Basic usage
```
d := versionedtext.NewVersionedText("The dog jumped over the fence.")
d.Update("The cat jumped over the fence.")
fmt.Println(d.GetPreviousByIndex(0))
// "The dog jumped over the fence."
fmt.Println(d.GetPreviousByIndex(1))
// "The cat jumped over the fence."
```
History can also be accessed by timestamps, more information in tests and in [the docs](https://godoc.org/github.com/schollz/versionedtext).
