- carelessDataset now has cogent column names

* changed vignettes

removed introduction vignette from package (now hosted online) and fixed typo with linking vignette

* changed psychsyn to do a resampling

psychsyn comes up with different correlation coefficients dependent on whether the item of an item pair is located at the x or y column.
