Star Database Program.

This is a more sophisticated assignment, it will take longer to do.

Write a program which uses file IO, loops, and function calls.

The following files are provided in pub:
Assignment.cpp
stars.dat
solution_stars.dat
solution.o

when you log in the first time, make a directory for this project
mkdir prog3

then copy down the files.  (WARNING! This will overwrite any file in
the directory named Assignment.cpp, so don't copy down Assignment.cpp
if you have already done work):

cp ~cs1253_pet/pub/prog3/Assignment.cpp Assignment.cpp
and so on, replacing Assignment.cpp with stars.dat, or solution_stars.dat,
or solution.o as needed.

Assignment.cpp is a starter that contains an int main function
as well as some function prototypes.
Your job is to write out the prototyped functions completely.
Do not change the int main function!

When you are done the command
~cs1253_pet/bin/p_copy 3
will submit the contents of the prog3 directory for grading.

by default the solution.o file is not executable, so you may need
to make it executable.  After copying it, the command:
chmod a+x solution.o
should make the file executable.

Your program should use stars.dat as a data file for input and output.
The solution program uses solution_stars.dat as a data file.
stars.dat is formatted to contain information as follows, separated by commas:

star name,star's constellation,star's apparent magnitude,star's mass,
star's diameter,next star's name, next star's constellation....

I will always give you a file that contains information in these 5 value 
pieces, so a given star will always be followed by a value for 
constellation, apparent magnitude, mass and then diameter.  Despite the fact
that some of these values are numeric, it would probably be easiest to 
use strings as variables as you will not need to do any math.

You do not have to test or worry about what happens if you start with a badly
formed file.  You DO have to ensure that you don't write to the file in 
such a way that it becomes malformed.

This program will, on open, display a list of names gathered from a CSV file.
The user will then select a name from that list, or "Add" or "Quit".
The names may have spaces in them.
If Quit is selected the program will end.
If a name is selected, then details about that star will be printed, and
then the menu will be reprinted.
If Add is selected the program will prompt the user to enter information
about a new star.
Note!  You must prohibit the user from entering the star's name as
Add
Quit
or any name that is already in the file as a star name.
Also!  The star information must be added to the file, so that it will persist 
and be present the next time the program is run!.
