In many cases where we have functionality that we might want to use
other than as a GNU Radio block, we create an implementation class,
which we then create a gr_ class that wraps around this to bring the
implementation into an actual gr_block. So in this case, both are
valid, but one is a gr_block the other is the algorithm used inside of
the gr_block.
