RE: [ajug-members]: Logic Assistance

[Webb Morris <webbmorris@yahoo.com>]

The reason I used the 01.00.01.00 example was becuase in your list below, you have an entry for
02.00.01.00.  Perhaps this was a mistake?

I think I follow your logic below, but I'm not 100%.  If it is true that all children must
increment the next zero position of their parent when created, then the logic could look like the
following for inserting a node "Above" the current node:

1. For current selection, find the last non zero position.  (For 01.01.00.00, this would be
position 2).
2. The parent of this node would have to be the node with a zero in this position and all
positions after it. (01.00.00.00)
3. The children of the parent node would have to be any node that had all the non-zero positions
of the parent node (position 1 equals 01, so 01.02.00.00 or 01.01.01.00 for example).
4. For all chidren whose value in the important position (the 2nd position in our example) is
greater than, or equal to, the given value in the selected node (01 in our example), increment
this and only this position (so 01.02.00.00 would become 01.03.00.00 and 01.01.01.00 would become
01.02.01.00)
5. Assign the current selections value to the new node (01.01.00.00)
