added support for iterating objects with [pass global]

Eliot,
I’ve created a version of CCS based on current code base which adds support to iterate objects using [pass global=x]. It supports (and fixes*) debug.

How can I send you this version or patches to consider merging with master? I’d like to send to you soon before another version is rolled out.

*the fix I applied to debug param: I found that debug was only working for $field_value when it was passed with array (explicit values) but did not debug print the array or object if it was dynamically pulled from $GLOBALS
