nmrfit_1d: Fit an NMRScaffold1d object to a set of data
In ssokolen/rnmrfit: Robust NMR Lineshape Fitting in the Frequency Domain

To do.

nmrfit_1d(object, nmrdata = NULL, normalized = TRUE, bounds = TRUE,
  coupling.leeway = 0, area.leeway = 0, satellite.leeway = 0,
  ordered.peaks = character(), include.convolution = TRUE,
  components = "r/i", opts = NULL)

`object`	An NMRScaffold1D object.
`nmrdata`	An NMRData1D object. Optional if the NMRScaffold1D object has the nmrdata slot set.
`normalized`	TRUE to use a normalized fit. If the parameters or bounds are not already normalized, they will be normalized to the data. If FALSE, previously normalized data will be rescaled before fit.
`bounds`	TRUE to use bounds (setting conservative bounds if none exist), FALSE to ignore any attached bounds.
`coupling.leeway`	Fraction of possible error in specified coupling constants. Switching to a non-zero value results in the use of inequality constraints.
`area.leeway`	Fraction of possible error in specified area ratios of coupled peaks. Switching to a non-zero value results in the use of inequality constraints.
`satellite.leeway`	Fraction of possible error in the symmetry of satellite positions as a function of the distance between a satellite and the main peak. Switching to a non-zero value results in the use of inequality constraints.
`ordered.peaks`	A vector of peak ids (names) whose order relative to each other is not allowed to change. This option can be useful for preventing an arbitrary collection of singlets used to fit a more complex peak from drifting past or on top of each other, leading to ill-defined optimization.
`include.convolution`	TRUE to include convolution vector of nmrdata into fit (if present), FALSE to ignore it.
`components`	String specifying the complex data componets to use for the fit (one of either "r/i", "r", or "i").
`opts`	NLOPT option list used to overried default values.
