*   UPDATE node epocutils for Emotiv EPOC SDK Community - XavG <xav.guerin@hotmail.fr> 2016
*
*   supposed to be used:  1 -> as a utility class ( include header file in necessary .cpp file )
*                         2 -> as a utility class, embedded in a library that is available system wide ( .so file )
