This was brought up on StackOverflow: http://stackoverflow.com/questions/41340086/how-to-cast-data-from-long-to-wide-format-in-h2o

It would be nice to provide a utility function to convert between long and wide format, since long format is very common in the stats community. This is the default format for "repeated measures" data (e.g. patient data where measurements are taken over time). https://en.wikipedia.org/wiki/Wide_and_narrow_data
