#
#  This demo call's usage to make a list of all defined routines
#  then it calls CallTree to make a call tree of program,
#  
#  We are generating a tree for the test program that is included 
#  (the test program has no real function) !.
#
#  the usage program is only used in this case to scan for defined functions
#  and the functions they call.
#
#  What will show up is that main call's newfunc and newfunc calls etrafunction
#   then extra function is called from main
