Description:
------------
It would be nice to have a "Reset" function for the parent DB_dataobject class, to completely clear all settings for the object.

This would allow DB object re-use.

Test script:
---------------
In my auto-generated extended objects, I have used the following to create a "pseudo-reset" that completely clears all the relevant search settings for an object. Its probably not the most efficient function, but works for all intensive purposes.

function reset(){
$subvars[]="";
//collect subs to ignore in our reset.
foreach (get_class_vars(get_parent_class($this)) as $key=>$value) $subvars[]=$key;
foreach (get_class_vars($this) as $key=>$value)
if (!in_array($key,$subvars)) $this->$key=null;
$this->_query['condition']="";
}

Sorry, the code should be:

function reset(){
$subvars[]="";
//collect subs to ignore in our reset.
foreach (get_class_vars(get_parent_class($this)) as $key=>$value) $subvars[]=$key;
foreach (get_class_vars(get_class($this)) as $key=>$value)
if (!in_array($key,$subvars)) $this->$key=null;
$this->_query['condition']="";
}

I'm curious though, do you incur any significant overhead of using clone versus simply reusing the same db object? In your first example, don't you essentially create 3 separate objects ?
