1. Objects in CLEO's Suez framework (Matt)


--------------------------------------------------------

1. See Matt's slide at:

Matt gave a brief overview of how the Suez data analysis framework
treats data/objects. Some of the benefits of objected oriented
design were discussed. Also presented was how the user interacts
with Suez to access data. 

Suez implements a new approach in the design of a data analysis
framework. Data is presented in the form of several streams. An event
is associated with a "frame" which represents a snapshot of all
streams at a partcular moment. It uses templates heavily for type safety.
The main program for Suez is generally not recompiled. Specialization
is done through loading shared objects. In fact, all analysis 
routines are implemented through shared objects. The exectuable itself
uses a Tcl shell. Configuration scripts are used to tell it which 
shared objects to load.
