1.  If you have Mathematica, you can open PRwRP.nb in Mathematica 
    and then open the mathematica source file.  You'll need to 
    redo the path for PRwRP.m so that it conforms to the directory 
    that you've placed it in before you can read it in.  

2.  To use the notebook, just evaluate the cells. 

3.  If you don't have Mathematica you can use it on Software Remote.
