	WordCount usage:

	WordCount -f filename [-l]

	if -l option is used program 
	prints each word in file one per line

	at end program number of words read is displayed

	Assignment - Program Modifications

        drop -l option 
        modify tokenizer to take into account punctuation =;().{}+-" etc.
	create output file with just words
        program should output characters for all words, words  and lines read
	if -f filename is not used program should print a warning message
