source using COMEDI
The source has one to many input stream of signed short integers.
Output samples will be in the range [-32768,32767].

ninputs | number of input streams connected |
noutputs | number of output streams connected |
This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.
Reimplemented from gr_basic_block.

The user must override work to define the signal processing code
