<P>
A lightweight Table-column <--> DataObject-property converter framework.
Converters allow a user to insert a transformation between a column value and
is destination DataObject property value. For example, by default, a VARCHAR
column will be represented as a String in its corresponding DataObject
property. A user could insert a converter that transforms the the VARCHAR
value to an Integer. If this is done then although the column returns
character data, the DataObject property will be an Integer
