All sorting stuff (sorts, shuffle, reverse) is extracted into Sorting/NSArray+EKSorting.
All sorting-methods are now in NSMutableArray to reduce a number of copy/mutableCopy garbage. This makes every algorithm much more readable compared to their previous NSArray variants.
Thank you for a such support and for all of contributions.
I am really "overtimed" on my current commercial project, & sadly, have no time for open source.
