Pipeline enables easy cascading of dataflow modules.
DataFlowGraph can eventually use it to implement the
add_pipeline method to avoid duplicating things.

Converter enables easy conversions of data width on dataflows.
It handles the 3 possibles cases:
- downconverter
- upconverter
- direct connection when data width are identical.
