Great!

That's not a Python file that is designed to be run from the command
line. It gets installed and provides helper hier_block2 classes to
make using the PFB code easier. So you would use it in a program like
filter.pfb.channelizer_ccf(...).

Look at the examples in gr-filter/examples, not at this file.

Yes, the QA code is our quality assurance code that is executed during
'make test'. But they can be useful to show you how to use the blocks.

The blks2 is a set of classes created in
gnuradio-core/src/python/gnuradio/blks2impl, including some of the
original PFB stuff that is now moved into gr-filter completely. Note
that we have deleted blks2 from GNU Radio on the next branch (and
therefore in 3.7), so this will all be replaced by things like
filter.pfb....
