)

`obj`	an object of class 'Landscape'
`nits`	integer value, the number of iterations for resolving the IFD
`couch`	logical, has the couch effect been calculated and present in slot 'couch' of the landscape object.
`startE`	logical, is the IFD calculation starting at previous effort vector in slot 'eff' of the landscape object (allows further IFD iterations)
`varind`	positive real number, the slope of the logit choice (low values are 'choosey' a value of 1 is proportional to utility)
`uprat`	fraction, When converging on a stable effort distribution this is the contributing fraction of new effort
`quiet`	logical, should warnings and messages be surpressed?
`shiny`	logical, should progress bar updates be provided (required for shiny app)
`Gmodel`	character, the density dependent growth model. Options are 'Lester1', 'Lester2' and 'New Lester'
