Added: src/java/org/apache/log4j/chainsaw/plugins
ChainsawCentral.java
Log:
Very rough check-in, but hopefully you can see where I am headed.
This plugin will have a graph window of the rate of events arriving in the
top right hand corner. (if you have seen GetRight's data transfer graph,
that is idea I am borrowing).
The message center is now within this panel.
