Word processors are computer programs which facilitate the composition 
of documents, papers, letters, etc.

     They often give the user direct control
     over layout of the printed page. In this assignment you
     will write a program that will implement one of the functions 
commonly found in Word Processors. 

These paragraphs illustrate what is required. The above paragraph is 
printed exactly as it was typed. The current paragraph was printed in 
'fill mode' with both margins justified. 
This means that each line contains a maximum number of words and each 
line is exactly the same length. In fill mode the text is analyzed 
before being printed to make sure that as many words as possible will 
fit on a line. If after putting as many words as possible onto a line 
to be printed, the line is less than the required length, extra blanks 
are added between some words to pad out the line. For further illustration 
the first paragraph is reprinted below in fill mode with both left and 
right justification.

found in Word Processors.

    Write a program to do the following:

    * Read an arbitrary text file into a two dimensional array. You 
may assume that the input file contains no more than 79 characters 
per line and no more than 50 lines.

    * Your program will fit as many words on each line as will fit 
without breaking any of the words as well as justifying the left 
and right margins.

    * The following guidelines should be used:
      A word is any sequence of non-blank characters bounded by 
white space with the obvious exception of words starting at the 
left margin or ending at the right margin.
      Multiple spaces and tabs should be treated as a single space.
      The end of a paragraph is signaled be an empty line. Multiple 
white space(s) or empty lines following an empty line will be reduced 
to a single empty line separating the paragraphs.

    * Write the array containing the revised text to an output file.
