Details:
     The idea was to make an easy-to-use and cross-platform way
     to compare the application sizes with 4.0, and also with any
     other points we need.

     Each 'application' checked is composed of a number of URLs.
     The URLs need to be determined separatedly (firebug is one good
     way to do this).  A property file contains a list of all
     URLs used for each application, along with previous sizes
     for comparison.  The previous sizes do not have to be present.

     The tool that does the checking is called 'netsize', since it
     looks at the actually bytes transmitted over the net, rather
     than file sizes.  It's a very simple HTTP client that just
     fetches URLs and looks at the size.  The only checking of
     content is to try to detect 404 errors that may show up as an
     error page.

     One suggestion was to fail the build if the apps grow by too
     much.  Perhaps we'll consider that in the future, but it's
     certainly easy enough now to check larger changes to track
     the effect on file sizes.

     The completes the requirement to collect baseline measurements
     against 4.0 and gives us tools to improves the sizes.
     LPP-6892 will be left open to track various improvement ideas.

Tests:
     After assuring that tomcat is running and that the app is deployed,
     in $LPS_HOME, ran:
        ant appsize
     to see that the file sizes have not changed since earlier today :-)
     Also ran:
        ant -Dappsize.input=appsize-4.0.txt appsize
     to see that the file sizes have changed somewhat since 4.0

     Other uses are detailed in test/appsize/readme.txt, including
     the -Dappsize.flags, -Dappsize.dir, -Dappsize.output and - 
Dappsize.branch
     options.
