* \brief Interface of a class that reads signals samples from a file
* and adapts it to a SignalSourceInterface
* \author Carlos Aviles, 2010. carlos.avilesr(at)googlemail.com
*
* This class represents a file signal source. Internally it uses a GNU Radio's
* gr_file_source as a connector to the data.
