> Looks good to me. I don't think it covers pathological cases like
`airquality %>% arrange(Temp) %>% head(10) %>% arrange(Wind)` or `airquality
%>% head(10) %>% tail(5)` but I'm pretty sure that's a given for our current
dplyr implementation anyways.
Those do work, though internally they can't be done in a single ExecPlan:
```
Table$create(airquality) %>%
arrange(Temp) %>%
head(10) %>%
arrange(Wind) %>%
collect()
Ozone Solar.R Wind Temp Month Day
1 NA NA 8.0 57 5 27
2 1 8 9.7 59 5 21
3 4 25 9.7 61 5 23
4 32 92 12.0 61 5 24
5 18 65 13.2 58 5 15
6 19 99 13.8 59 5 8
7 NA NA 14.3 56 5 5
8 NA 266 14.9 58 5 26
9 NA 66 16.6 57 5 25
10 6 78 18.4 57 5 18
Table$create(airquality) %>%
head(10) %>%
tail(5) %>%
collect()
Ozone Solar.R Wind Temp Month Day
1 28 NA 14.9 66 5 6
2 23 299 8.6 65 5 7
3 19 99 13.8 59 5 8
4 8 19 20.1 61 5 9
5 NA 194 8.6 69 5 10
```
