/**\class edm::StreamContext
Description: Holds pointer to ProcessContext, StreamID,
transition, EventID and timestamp.
This is intended primarily to be passed to Services
as an argument to their callback functions. It is also
used internally by the Framework to hold information
that can be added to exception messages about the
context where an exception was thrown.
