[Kst] Re: Fits

[C. Barth Netterfield]

The other option is for the fit dialog to create a kst plugin, then create a 
kstcurve.  Then to edit curve props, edit the curve.  To edit plugin props, 
edit the plugin.  Essentially, the fit dialog is just a convenience dialog 
(in the spirit of the data wizard).

BUT: There appears to be an issue with editing plugins in general: 
	if you edit a plugin (change its type), then old vectors used by existing 
curves appear to become orphans. (George?).  With plugins, it seems to me 
that the only option is to prevent any plugin whose vectors are being used in 
curves from having its plugin type changed.

BUT: a fit need not have any such restriction - the X and Y output vectors 
always exist, so one should be able to change the fit at will.....  And the 
current architecture could allow that.

BUT: in the current architecture, a fit 'has a' plugin, so they both show up 
in the data manager.  This is not good.  

Let's come to a consensus though, before more hacking.  I'm meeting w/ George 
tomorrow.  Can we call?
