This demonstrates the new boxplot functionality.

It trys to create 5 figures, each with 4 subplots. Only the first
    fourth figures should work. The second and third figures are 
    supposed to fail as the number of user-input medians and 
    confidence intervals do not match the number of columns 
    in the data. 

The first working figure plots all of the data with and without
