Hi,
I have a question about Dict().
I found there are no method such as sort_by() after v0.3.
But I want to count word frequency with Dict() and sort by its value to
find frequent word.
So, how can I sort Dict efficiently?
Of course, I know sort using DataFrame like following,
```
counts = Dict{String, Int64}("apple" => 100, "town" => 250, "space" => 24)
df = DataFrame(word = collect(keys(counts)), count =
collect(values(counts)))
sort(df, cols = [:count], rev = true)
```
I think it is natural `convert(DataFrame, dict)` returns Nx2 DataFrame
instead of 1xN one.
Thanks,
