{Create and Drop a Database}
{
 This test first attempts to create a database without specifying any parameters
 (should fail). It then goes on to create and drop a database, print out the
 parameters and then creates it again (will fail if the dropdatabase failed silently.

 Some basic database info is then accessed and printed.

 A basic query is performed and finally the database dropped.
