/*
* Nested_blocks:
* Nested Block processing is used to implement both imposition and
* personalization with Blocks:
*
* - The first-level Block container page contains several large PDF Blocks
* which indicate the major areas on the paper to be printed on. The
* arrangement of PDF Blocks reflects the intended postprocessing of the
* paper (e.g. folding).
* - Each of the first-level PDF Blocks is then filled with a second-level
* container PDF page which contains Text, Image, or PDF Blocks to be filled
* with variable text for personalization.
*
* Required software: PPS 9
* Required data:
* - first-level Block container with PDF Blocks named "Block_"
* - second-level Block container with arbitrary Blocks
* - variable data for filling second-level Blocks (provided in an inline array)
