Creates an instance of a psyFitset object

1	newpsyFitset(type = "CG", xx, pp, getPred, residFun, fnJacob, fnStart)

`type`	string expliciting which of three available fitting functions will be used. "CG" for cumulative Gaussian, "LN" for lognormal and "PL" for pseudologistic.
`xx`	quantity on the x axis (e.g. duration). Must be a vector of numerics
`pp`	quantity on the y axis (e.g. proportion of long responses). Must be a vector of numerics AND of the same length as xx.
`getPred`	Function that returns the predicted value.
`residFun`	Function that returns the residuals.
`fnJacob`	Function that returns the jacobian of the function to be fitted.
`fnStart`	Function that returns the starting parameters.

A psyFitset object for furture fitting.
