kst needs an interactive arbitrary function fitter.  

One where you could put in an arbitrary equation (parsed similar to regular equations, I assume), tell the fitter which variables in the equation are input vectors (and which actual vectors to associate with them), and which variables are parameters to fit.  Then for each parameter, you can give it an initial guess and indicate whether you want that parameter to be varied with the fit, or to remain constant.  Then the ability to iterate by 1, a few, many steps (or until the solution converges).  All the while, when possible, the fit solution curve would be shown in the plot (and updated even when the user just changes initial guess parameters or whatever), to keep the user informed on how their fitting is going.
