More tomcat Statistics...

[anita kulshreshtha]

Aaron, Joe and Others,
     I am attaching WebModuleStats that are available
for an app from tomcat. Should we define another
....TimeStatstic to deal with static time data? The
following  
long getProcessingTime(), 
long getStartupTime(), and
long getTldScanTime()
   fall under this catagory.

Thanks 
Anita
