Log Message:
Major refactoring to support parameters in SQL.  Also, SQL generation is
now more "strongly typed", so that e.g. you can't use an expression where
a table is wanted, or a condition where an expression is wanted, etc.  Also
added an interface for SQL generation, as a basis for creating a driver
framework.
