+ in the interest of robustness, I added

  utility.c :: cstring_alloc()
  utility.c :: cstring_lineFromFile()	/* they're at the bottom */
  so that I could read in lines of arbitrary length from FILE*s
  (instead of using fgets(huge_ass_buffer,...)).
+ I tested it out on sort, and it seems to be fine.
