There's no output with 100/50 either, because the default text we use at
WordCountData.WORDS is not very long and cannot satisfy the count window size.
There's only 11 window ouputs even with 10/5, which are still a bigger size.
I prefer 4/2, but also think 10/5 is also ok, because the program is for
demo purpose and new users would doubt the program's accuracy if it doesn't
generate enough output. What do you think? @zentol
> WindowWordCount example doesn't print countWindow output with default configs

> Fix For: 1.4.0
>
>
> When running WindowWordCount example with no params (using default params),
> no output is generated and thus printed, because the default 'window' and
> 'slide' value is too large (250 and 150).
> The solution is to lower default 'window' and 'slide' values to probably 4
> and 2
