Currently, a histogram can only be created for one column at a time. It would be useful to create one plot that contains histograms for all columns in a Table.

Desired solution

• Add a method plot_histograms (note the s) to the Table class
• The method should place the histogram for each column in a grid
• It should be clear which plot belongs to which column

seaborn should already have a method to create a grid. If that's not the case, matplotlib definitely has one.
