possible solution steps

1. one vertical text area/ div to reflect the history
2. one text box fro the object, pulldown for the commands and another text box for args
3. one div for the puzzle


the puzzle is as follows
generate an NXN array of divs each with a unique i,j id.

genearte 2n divs for the row and col identifier tabs..
and n more divs for the block identifier tabs

clicking on any div will add its id to the object text box
except when super seded. ie if you select a cell and a row containing that cell, the cell handle is removed and the row handle is added.

more later..
