Detailed Description

Load a pair of input BitSeries using ParallelBitSeries from a pair of parallel Inputs.

This class extends the ParallelInput based class is configured by a descriptor which defines a subsequent pair of singular Inputs. The singular Inputs support classes derived from dsp::File.
