The idea of this assignment is to produce a script called "out" which
is a bit like cat but contains some (weird) features.
These features are requested by use of flags.  You do NOT need to
retain the other features of cat.

Here are the features:
	1. Out the file(s) entirely in capitals. Use -C
	2. Out the file(s) double spaced.        Use -2
	3. Out the file(s) with the lines numbered. Use -n
	4. Out the files with the lines numbered separately by file. Use -N.
	5. Out the files into the file denoted by: -f file.

Notes
1.	The references to "file(s)" are because this program, like most Unix programs,
should allow multiple files to be done at once.  E.g. out -C file1 file2

2.	You should allow mixes of the flags such as:

		out -2C -f foo -N file1 file2

3.	The session below is designed to show the difference between out -n
and out -N
