Proposal for Compression Filter example

[Amy Roh]

Hi,

I created an example web application using Filter technology and would like to 
add to Tomcat 4 example webapps.  This example includes Data Compression Filter 
which compresses ServletResponse according to the threshold that can be set by 
users.  I think it'll be a good example usage of filters.

What do you think?

Cheers,

Amy
