Elm Step Sorter is Elm code you can use to sort a list in your web application.
mergeSortStep returns a Result of either the sorted list, or an intermittent step. You can call choices on an intermittent step to get a pair of elements that are currently being sorted. You must provide an Ord to your calls to mergeSort, ordering that pair, in order to progress sorting.
There is also a demo app showcasing the algorithm. It is deployed on github here, or you can clone and build the demo with elm-make.
