I think the goal of these handlers is to be able to use a key to lookup the full
object in the returned Map.  So if you used the primary key column as the map
key you would be able to lookup the object in the map based on the primary key.

Rather than have a handler class for each type of object being stored in the map
it might be better to have one class with a protected method that generates the
object.  The default behavior could be to generate a Map for the row but users
could override that to generate a bean, arrray, etc.  Maybe the class could be
named KeyedHandler.

DbUtils' minimum Java version is 1.3 so LinkedHashMap can't be used in the
default implementation.  Again, we could provide a protected factory method that
users on 1.4 could override to return a LinkedHashMap.
