[Clas_cascades] Analysis Note Update

[Lewis Graham]

Hi,

I am still making final changes to the Analysis Note but it mostly 
finished  besides adding some text so I wanted to go ahead and have 
everyone look over it and give me needed changes or additions.   It's on 
the wiki, I put the link below.  Thanks,

Lewis
