"""Similar to the Python reduce function, applies a rolling computation to
sequential pairs of values in a list. The ``din`` input is of type
:class:`Queue` which holds the values to be used for computation while the
``cfg`` input is a :class:`Tuple` consisting of a ``reduce_size`` field and
the ``init`` field holding the inital value.
Args:
f: Function to be performed
max_size: Maximal length of the input `Queue` which is the depth of the
FIFO used for storing intermediate values
Returns:
The result of the reduce operation
