cameo: moved tool compensation from cameo.c to ops.c

Browse Source 
- Makefile (OBJS): added ops.o
- cameo.c, ops.h, ops.c (process_path, process_paths): moved from cameo.c
  to ops.c
- ops.h, ops.c (process_paths), cameo.c (main): renamed process_paths to
  tool_comp_paths
- ops.c (process_path, tool_comp_paths): renamed process_path to
  tool_comp_1
