Added and updated maintenance files:
show.R: corrected display behaviour for DET objects.measures.R: added objects to the output of minDcf().plot.R: corrected DET and ROC curve plots with confidence intervals, axis labels, and zoom options.detc.R: corrected the names of the positive and negative labels.Small code modernisation and polish.
Added class objects to model DET curves.
Overrode the standard plot() function when called with a DET or DETs object.
Renamed printDET() to show().
Added new functions to compute performance measures: EER() and minDcf().
Added new functions to plot the corresponding ROC curve from a DET curve: plotROC() and plotROCs().
printDET() shows the names of the classifiers used to access the DET object.
detc() and detc.CI() do not plot the EER. The examples describe how to do this.
Added the speaker and ovarianCancer data sets to provide real examples of DET curves.
Added printDET() for describing the DET returned parameters.
Renamed det() and det.CI() as detc() and detc.CI() to avoid overriding existing functions.
New detc() and detc.CI() functions now provide an estimate of the Equal Error Rate in the returned data frame.
Updated the appearance of ROC curve plots.
det() and det.CI() now include xlim and ylim arguments to select the axis limits of the plot.
