// output_file_open() and input_file_open() are safer versions of
// using open().  When you open a file for output, if that file
// already exists you will overwrite it and loose its previous
// contents.  Not good. So output_file_open firsts check to see if
// the file 'filename' exists.  If it does, then output_file_open
// returns false, which means failure. If it returns true, then
// the file was successfully opened, and the fout stream should
// be ready for writing.
