an S3-list of class "gmTurningBands" containing the few elements given as arguments
to the function. This is just a compact way to provide further functions such as predict_gmSpatialModel
with appropriate triggers for choosing a prediction method or another, in this case for triggering
turning bands simulation.
Arguments
nsim
number of realisations desired
nBands
number of bands desired for the decomposition of the 2D or 3D space in individual signals
seed
an object specifying if and how the random number generator should be
initialized, see ?simulate in base "stats" package
