Hello World

From $NEMO/src/tutor/hello/hello.c we quote a NEMO version of the infamous hello world program.

/*
 *  HELLO:  Example of ``hello world'' using NEMO 
 *
 *  With the $NEMOBIN/cc script it should compile as follows:
 *             cc -o hello hello.c -lnemo -lm
 *
 *      ??      V1.0    Created                 Peter Teuben
