*
* Usage:
*
* 1. Paste this as new plugin and connect it to system event
* 'OnDocFormRender'.
*
* 2. Assign a new TV 'changeTemplate' to each template
* for which you want to define the default children template.
*
* 3. Set the newly created TV to input type "Text"
*
* 4. Open a document and in the 'changeTemplate' TV type a
* comma separated list of template IDs.
*
* 5. Have fun!
