Add ability to add multiple items/build data structures easily.

For 2-4 Tree, "6,10,14|1,2,3|7|12,13|15,16" to

The underlying functionality is still needed as Jack described above - i.e. some method or functionality within each page to add an array or string of data into the structure or algorithm instantly. But we want to focus on this data being passed via the URL, so that users can share URLs for pre-set examples or save an example, etc.
