Uses standard error of estimated recruitment deviates to estimate the 5 controls for the bias adjustment in Stock Synthesis

SS_fitbiasramp(replist, verbose = FALSE, startvalues = NULL,
  method = "BFGS", twoplots = TRUE, transform = FALSE, plot = TRUE,
  print = FALSE, plotdir = "default", shownew = TRUE, oldctl = NULL,
  newctl = NULL, altmethod = "nlminb", pwidth = 6.5, pheight = 5,
  punits = "in", ptsize = 10, res = 300, cex.main = 1)

`replist`	Object created using `SS_output`
`verbose`	Controls the amount of output to the screen. Default=FALSE.
`startvalues`	A vector of 5 values for the starting points in the minimization. Default=NULL.
`method`	A method to apply to the 'optim' function. See ?optim for options. Default="BFGS". By default, optim is not used, and the optimization is based on the input `altmethod`.
`twoplots`	Make a two-panel plot showing devs as well as transformed uncertainty, or just the second panel in the set? Default=TRUE.
`transform`	An experimental option to treat the transform the 5 quantities to improve minimization. Doesn't work well. Default=FALSE.
`plot`	Plot to active plot device?
`print`	Print to PNG files?
`plotdir`	Directory where PNG files will be written. By default it will be the directory where the model was run.
`shownew`	Include new estimated bias adjustment values on top of values used in the model? (TRUE/FALSE)
`oldctl`	Optional name of existing control file to modify. Default=NULL.
`newctl`	Optional name of new control file to create from old file with estimated bias adjustment values. Default=NULL.
`altmethod`	Optimization tool to use in place of optim, either "nlminb" or "psoptim". If not equal to either of these, then optim is used.
`pwidth`	Default width of plots printed to files in units of `punits`. Default=7.
`pheight`	Default height width of plots printed to files in units of `punits`. Default=7.
`punits`	Units for `pwidth` and `pheight`. Can be "px" (pixels), "in" (inches), "cm" or "mm". Default="in".
`ptsize`	Point size for plotted text in plots printed to files (see help("png") in R for details). Default=12.
`res`	Resolution of plots printed to files. Default=300.
`cex.main`	Character expansion for plot titles.
