* \brief This interface represents a GNSS block.
* \author Carlos Aviles, 2010. carlos.avilesr(at)googlemail.com
*
* Abstract class for GNSS block interfaces. Since all its methods are virtual,
* this class cannot be instantiated directly, and a subclass can only be
* instantiated directly if all inherited pure virtual methods have been
* implemented by that class or a parent class.
