fitCauchy(x, y, center, hwhm, height, yoff)

fitCauchy2(x, y, center, hwhm, height)

`x`	A numeric vector. The x-axis of the data to be fit.
`y`	A numeric vector. The y-axis of the data to be fit.
`center`	A numeric. A starting guess for the center of the Lorentzian.
`hwhm`	A numeric. A starting guess for the half-width at half-max of the Lorentzian.
`height`	A numeric. A starting guess for the ampltidue scaling of the Lorentzian.
`yoff`	A numeric. A starting guess for the offset from the y-axis.

This function calculates the Lorentzian/Cauchy fit of the provided data. It uses dcauchy to calculate the Lorentzian/Cauchy profile and optimizes it. This version contains a y-offset optimization.
