[higgins-dev] RP code checked in

[Greg Byrd <gbyrd@xxxxxxxx>]

I checked in the code for the RP developed by Bruce Rich.  There's an 
authentication filter in:

app/RelyingPartyDemo

And an application that uses the filter in:

app/RelyingPartyDemoApp

(I'm happy to rename/move these later, if desired.)

I've included the JAR files required for each.  The RelyingPartyDemo 
also requires a servlet runtime library.  (I used Tomcat 5.5.)  
Questions about installing/running should be directed to Bruce.
