Think UNIX pipelines: ls -l | sort | gzip > /tmp/blah

1 stage == one operation over the data. ls is provider fo sort which is
provider to gzip.

i want to mimick the same in C++. each stage consumes data until its
provider has some, does some processing on the data and feeds the result
to its consumer (but only when its consumer asks it to provide the data
- - the model is consumer-driven).

but I need more powerful semantic: each stage can have more than one
input, it can feed its output to more than one stage and types on input
and output may differ.

is it a bit clearer now?
