> The main idea to add a few strategies of indexing: sorting and so on.
> Currently it supports only one strategy (most popular with zero and less popular with
the max index size).
> There are can be a few options
>  * 'frequencyDesc': descending order by label frequency (most frequent label assigned
0)
>  * 'frequencyAsc': ascending order by label frequency (least frequent label assigned
0)
>  * 'alphabetDesc': descending alphabetical order
>  * 'alphabetAsc': ascending alphabetical order
>  
> Please, update the method **transformFrequenciesToEncodingValues and add the strategy
as a parameter of trainer.
