simple SQL-building library

 SQL::Tiny is a very simple SQL-building library. It's not for all SQL needs,
 only the very simple ones.
 .
 SQL::Tiny is for generating SQL code for simple cases. It doesn't handle
 JOINs. It doesn't handle GROUP BY. It doesn't handle subselects. It's only
 for simple SQL.
 .
 The trade-off for that brevity of code is that SQL::Tiny has to make new SQL
 and binds from the input every time. You can't cache the SQL that comes back
 from SQL::Tiny because the placeholders could vary depending on what the
 input data is. Therefore, you don't want to use SQL::Tiny where speed is
 essential.
