uh...sure...if i ever finish! : ^ )  ... it's a weekend project, and may not
ever get finished (depends how much time i've got on my hand after class and
work...  maybe a christmas project! : ^ )

as far as output, i've been using cout and will (once i do some more work on it)
incorperate the setiosflags() statements and stuff...  i've found them to be
fairly easy...

linked lists?  what exactly is that?  i realize the problem with arrays, but as
far as my c++ knowledge goes (i'm at midterm of my first ever c++ class), that
seems most logical... better than 50 billion char variables! : ^ )

input one line then output?  meaning like (in the final version) input one
filename, then print that to the output file, then read the next, concat it,
blah blah blah?
