* Short term
** TODO document much more, using Roxygen headers
** TODO fix critical use of switches without stops
** TODO R files to improve on
TODO CopulaAC.R
TODO CopulaGauss.R
TODO CopulaStudent.R
TODO Correlations.R
TODO Credit.R
TODO Defunct.R
TODO Gauss.R
TODO GEV.R
TODO GHYP.R
TODO GIG.R
TODO GPD.R
DONE Gumbel.R
TODO NH.R
TODO PlotFunc.R
TODO PointProcess.R
TODO POT.R
TODO Student.R
TODO Utility.R
** TODO put in improved version of QQplot
** TODO put several R files together
** TODO improve on .Rd
** TODO POT.R is a major part but requires much more work => separate figures and computations!
** TODO Plot functions in POT.R: Explicitly set arguments for internal calls to plot as NULL and provide in function body default values. More freedom for user and passing of ellipsis argument.
** TODO POT.Rd does not describe any return objects! In particular, fit.GPD()$data contains the exceedances, not the original data (the latter should be renamed to 'x')
* Mid term
** TODO update data sets (pointed out by Giovanni 2013-04-12), bring in new ones, use proper data format
** TODO replace as much as possible concerning copulas by proper function from package 'copula'
** TODO largely improve on the code quality
