perform fit process with IDL CURVEFIT
iterations - (optional) Number of iterations to perform before query to prolong.
selected - Apply fit to selected data points only.
All options may be set with the "set" command. The command prefix is "curvefit".
Seems to produce better hessian errors but may fail to converge if data errors are not estimated properly. Tied/bound parameters are not supported. It is recomended to use the fit command instead which uses the mpfit library. This command was added for cases in which the mpfit library is not available but the cafe environment should be used nevertheless.
Changes parameter values/errors in environment according fit result.
> model, "sin+lin", 2 > curvefit -> fit result
