[plt-scheme] The or-pattern in match.ss

Hey guys,

I have done some work on the pattern matching library match.ss.  It
appears to working quite well now.  If you would like to try it out
it is at:

http://sol.cs.wcu.edu/~bhauman/scheme/pattern.html

The library is not done, but it appears to be functioning much better
than it used to.

I am new to macros and  hygenic macros and this has been a great way to
start to get aqainted with them.  I welcome all and any comments on this
code.  I am really trying to learn this stuff.

Thanks,

Bruce Hauman
