Adding SUMMARY statement to HPL/SQL to describe a data set (table, query 
result) similar to Python and R.

For each column output the data type, number of distinct values, non-NULL rows, 
mean, std, percentiles, min, max. Output additional stats for categorical 
columns. This helps perform quick and easy explanatory data analysis for SQL 
devs and business users.
