Create a script which can generate CSV from a database table

This should be relatively easy - just use the parameter framework in place, and use csv.writer() and db.execute2() to put out a CSV file.

The script should be named "sql2csv". It should take similar parameters to the standard "csv2sql" tool, and the user should be allowed to specify various database options, including username, password, etc. The database and table names should be required.

The script should copy the column header from the table, then proceed to take the data from the database. It should ensure that the data is properly escaped (according to the CSV standard -- this may be provided by the Python csv module).

This could probably be based on a modified version of "csv2sql".
