Description

.. start_description

Number of nested activate blocks.

Computation
===========
The metric uses a recursive algorithm to determine the maximum number of nested conditional blocks.
It traverses nested state machines to look for enclosed conditional blocks.

A conditional block with no nested sub-block has a depth of ``1``.
