For loop example COUNTER 10 > 1 -2.5, expect 10, 7.5, 5, 2.5
#for COUNTER 10 > 1 -2.5
  COUNTER
#endfor

Test of nested loops, expect outer 10,8,6,4,2, inner 2,3.5,5
#for	OUTER    10 > 1 -2
# for INNER 2 <= 5 1.5
   outer=OUTER, inner=INNER
# endfor
#endfor

Test of macros in for line, expect 100,102,104:
#define START_VAL 100
#define END_VAL 105
#define INC_VAL 2
#define COMPARE_VAL <
#for TESTER START_VAL COMPARE_VAL END_VAL INC_VAL
  TESTER
#endfor

Test of loop break out, expect 1,2,3,4,5
#define END_LOOP 10
#for LEAVE_LOOP 1 < END_LOOP 1
 LEAVE_LOOP
# if LEAVE_LOOP >= 5
#  define LEAVE_LOOP END_LOOP
# endif
#endfor

Test of include files in loop, expect 0.1,0.2,0.3
#for INCLUDE_LOOP 0.1 <= 0.3 0.1
# include "test.h"
#endfor
End loop value should be 0.4: INCLUDE_LOOP
