#2 Should be able to transform a whole repetition

[C. Studer]

I should add ability to transform a whole repetition
(recursively) with only one <transform> statement.

Example:

<template>
...
<transforms>
<transform variable="module.items" rule="xxx"/>
</transform>
</template>

where module.items might be something like:

module['items'][$i] =
array('title'=>'bla','subitems'=>array(...),'id'=>$i);

Currently, this does not work as I just don't know when
I should transform the repetition. Should I transform it

1. when we start iterating through module.items
2. seperately for each item (inside the iteration loop)
3. when we retrieve a scalar value inside the
module.items-branch
