A DESCRIPTION OF THE PROBLEM :
I think a lot of people write the following code to get tomorrow and yesterday.

```
LocalDate tomorrow = LocalDate.now().plusDays(1);
LocalDate yesterday = LocalDate.now().minusDays(1);
```

I think supporting tomorrow() and yesterday() functions will make it more convenient, meaningful, and more readable.

For example we can get 'tomorrow', 'yesterday' like following code.

```
LocalDate tomorrow = LocalDate.tomorrow(); // or LocalDate.tomorrow(zone); or LocalDate.tomorrow(clock);
LocalDate yesterday = LocalDate.yesterday(); // or LocalDate.yesterday(zone); or LocalDate.yesterday(clock);
```
