                              kwic index in Java

The objective of this assignment is to use your OpenList java library
to support the port of the kwic index program (a02.rex) to Java.
You may use either your rex version or mine.  It will be easier for me
to help you, however, if you use mine.

The Java version is different in its interface from the rex version in the
following ways:

    1) The Java version titles come from the standard input, one per line.

    2) The Java version noise words are from a file, one per line,
       the name of which is specified on the command line.  If there is
       no name specified, then there are no noise words.

    3) The Java version number of left and right spaces come from the
       command line, following the name of the noise file.  The number
       of left spaces can only be specified if the noise file name is
       specified.  The number of right spaces can only be specified if
       the number of left spaces is.  The default is 35 spaces.  These
       do not count the space in the gutter, the colon, and the reference
       number.

Example:

On the command line:

    java kwic noise1.noise 35  25 < kwictest1.in

Suppose noise1.noise contains:

The first thing we do let's kill all the lawyers.
Throw physic to the dogs; I'll none of it.
We are such stuff as dreams are made on.
To thine own self be true.
We know what we are, but know not what we may become.
For in that sleep of death, what dreams may come.
It is not in the stars to hold our destiny, but in ourselves.
Sweet are the uses of adversity. 

Then the output would be:

              Sweet are the uses of adversity.               : 7

If the noise file name is non-existent, you kwic should terminate with an
error message:

> java kwic foobar
*** No such file for noise: foobar

If either of the space numbers is not a number, your program should
so-indicate:

> java kwic noise1.noise foo < kwictest1.in
*** Invalid integer specified: foo


There is a runnable set of class files in /cs/cs60/a/04 that you
can use for comparison with your own.  There are also at least three
input test files and a noise file in that directory.
