Descriptive information of a Categorical

The .describe() method on a Categorical will produce descriptive statistics in a manner similar to Series or DataFrame.

The result gives us the number of instances of each category and the frequency distribution of each.

The count of values for each category can be obtained using .value_counts().

And the min, max, and mode values are found using the respective methods.
