Get simulations for a factorial experiment

## Examples

```
wheat <- read_apsimx(system.file("extdata/wheat.apsimx", package = "rapsimng"))
permutation <- search_path(wheat, path = "[Factors].Permutation")
get_simulations(permutation$node)
#> $V
#> [1] "1" "2"
#>
#> $Cv
#> [1] "Axe" "Bolac" "Calingiri"
#>
#> $N
#> [1] "0" "200"
#>
```
