Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Broke my head with trying to go though the list of coordinates.
But the func should receive only one pair of coordinates.
It will be good to make instruction more clear.
But honesly my pattern of regexp was not completely valid (as it was my first experience with re), so now I know more about regexp.
Thanks to all!:)
