I have some tab controls that I created in this app.

On startup the records for the tabs are pulled from SQL order by a sequence column. The sequence
number is stored to an iIndex property on each tab.

Assume that the user wants to move the tab 'Tools' between 'Home' and 'Project', or 'Schedule' after
'Resource'.

I am not going to be writing out to SQL again until the user clicks 'Save' at some point, so going to
the data is out, but I need to be able to reorder the controls interactively at run-time.

I'm having trouble coming up with the algorith for this. Can anyone help?
