Plot ROC Curve for a Dataset
rocPlot will plot an ROC curve (and return the AUC) that describes how well a gene signature (as defined in a
filterObject) classifies groups in a dataset (in the form of a
a MetaFilter object containing the signature genes that will be used for calculation of the ROC plot.

Title for the ROC plot.
Evaluates the ability of a given gene set to separate two classes. The gene set is evaluated as a Z-score of the difference in means between the positive genes and the negative genes (see calculateScore). Returns a standard ROC plot, plus AUC with 95% CI (calculated according to Hanley method).
Returns a ggplot2 plot object
