[Greg Monroe <Gr...@DukeCE.com>]

Torque meta info is contained in the Map classes.

You can get the TableMap object via getTableMap() 
methods in both the Peer or Record objects.  
This contains ColumnMap objects (and other linked
info) with Column specific names.

However, for convenience, the Java column names
are also contained in an array property of the
Record objects.  These can be used with the
getByName/setByName methods to quickly walk
thru the object values.

One "gotcha" with the Map data to be aware of is
that the DatabaseMap structure which holds the
TableMap objects is populated only if a Table
peer object is created. If you need to ensure
that the DatabaseMap object has all the tables,
you have to call it's initialize() method.

See the Javadocs for the possible problems with
this method.
