Change difficulty levels

[AmjadHD]

AFAIK Currently all exercises are tagged easy except for one (react), there should be better categorization of exercises by difficulty.

@AmjadHD yes you are right!
Currently, the exercises in nim need a lot of updating.
Would you like to take a stab at it?

[AmjadHD]

What needs updating exactly ?

[ynfle]

Our track's specific config.json contains all of the information for our track including the difficulty of all of the practice exercises.
The specification for the config.json can be found on the docs on the website here.
For each practice exercise, there is a difficulty key that is defined as a number.

In general, the ideal way for the track to be structured is to have concept exercises and corresponding practice exercises. Unfortunately we don't have any of those yet...

yeah thanks, I'm already preparing a PR for this.
I'm yet to read the docs to understand more those concept exercises.

Ok great!
If you'd like to help out in any way, let us know! We'd love contributors to the nim track.
