The MixMatcher tool is designed to make it easier to try out different
combinations of components.  It allows you to use your own components, the
demo components provided with the project, and solutions turned in by
other students.  It retrieves the demo solutions and other student
solutions directly off our web site (although these are NOT currently 
updated in real time).  


To use it:
1) download the MixMatcher.jar file.
2) You can place it anywhere, but I SUGGEST placing it just outside
the directory holding the project 7 directory tree.  
3) Double-click the .jar file, or if that doesn't work run it from
a console using the command "java -jar MixMatcher.jar".  
4) In the file box that pops up, select the directory which contains 
the mvc143, bussim, and horoscope subdirectories.  
5) In the next box, select which application to run.  You should now 
be presented with a list of components.  
6) Click the check boxes to select one component from each Module.  
7) Press run to run this combination.  


Note that this tool is still experimental and
has some rough edges.  In particular, there is no way to terminate 
applications that don't terminate themselves.  Additionally, since
System.exit() would get rid of the MixMatcher program in addition to
the program being run, it is blocked.  If you see an Error 
"java.lang.Error: Blocked attempt to exit", this is just informing you
that the program being run tried to exit, but wasn't allowed to do so.
