perfsonar development work

["Jeff W. Boote" <>]

I have added some documentation to the wiki to help explain what the 'value' of 
the eventType element should be. (Currently, everyone is using ad-hoc names such 
as 'utilization' and 'select' etc..)

http://wiki.perfsonar.net/jra1-wiki/index.php/Generalities

I also tried to explain the format of a message a little more clearly. This page 
existed before, but did not have very much content. Hopefully no one minds that 
I added to it.

The non-namespaced eventType values should eventually be migrated.

The migration should take the normal route: Be forgiving in what you accept, and 
strict in what you send.

In other words, services should accept both old and new names for a while in 
requests. (And respond with which ever version they are sent.) Once services do 
this, clients should be modified to only send the new names. Eventually, the old 
names can be removed from services.
