An SQL Builder, Object Interface to Database Tables
DataObject performs 2 tasks:
1. Builds SQL statements based on the objects vars and the builder methods.
2. acts as a datastore for a table row.
The core class is designed to be extended for each of your tables so that you put the
data logic inside the data classes.
included is a Generator to make your configuration files and your base classes.

- fix bug #23712 - deleting (and probably updating as well) an object while
being fetched. (Michael McCarthy for spotting this)
- fix generator overwriting code when file was edited in a Windows editor
(Robert Janeczek)
- validation will not produce errors on empty numeric data by default.
- overload extension enabled to relay setFrom and toArray calls to get*, set*
methods, which are predefined as
getXXX = returns $object->XXX
setXXX($V) = returns true (or an error string if you create your own)
(only affects php-4.3.2RC2 or later..)
- selectAs($dataobject,'prefix_%s') to help control the way join queries return
their data * doing selectAs() - clears the select and sets it to table.id as id ... etc.
- joinAdd has 2 extra optional arguments
$dataObject->joinAdd($otherDataObject, $joinType, $joinAs)
existing behaviour (INNER Joins) is default (eg. no value)
$joinType can be:
INNER,LEFT,RIGHT = eg. INNER JOIN ... etc.
'' = just added with a , and the link conditions are added with a WHERE statement.
$joinAs can be used to name the table differently in the join eg.
SELECT .. FROM person INNER JOIN address as homeaddress ......
- setFrom has an extra optional parameter for formating: eg.
$object->setFrom($_POST,'prefix_%s') would map prefix_name to $object->name
the default is '%s' which is the same as the previous behaviour
- added option dont_die (default no) to ini file
default (no) means that DataObjects will emit a PEAR_ERROR_DIE on configuration and
programming errors
true or 1 means that you can write a PEAR::error handler to catch the errors and
display a nice it's not working message
