Take a CSV file, query it with SQL. Magic!
$ cargo run file.csv
Loaded 3162 rows into t(domain, base_domain, agency, sslv2)
> SELECT COUNT(*) FROM t
+----------+
| 3162 |
+----------+All your rows go into a table named t. It's great!
You can also specify multiple files:
$ cargo run file1.csv file2.csv
Loaded 12 rows into t1(some, schema)
Loaded 74 rows into t2(some, other, schema)
