[Newbies] More squeak tutorials: simple algorithm visualization tool

I'm working on a tool to visualize simple algorithms and data structures for my tutorials

Currently, it only supports display of Array>>at: #at:put: #wrapAt: #wrapAt:put:

in the near term, I'm working on the display of operations on the the elementary data structures like linked lists, trees, etc, with the elementary algorithms for sorting/searching/insert/delete/etc.

I'm refactoring as I go. The second iteration still needs much work even within the context of Array methods.

Suggestions/comments/criticisms welcome, thanks.
