Include Systems

["Peter Gibson" <Peter_Gibson@xxxxxxxxxxxxxx>]

Within an IncludeSystem I want to refer to data which is initialized on the
first bar.  On bar 1 I want to store certain constants to variables so I can
refer to them on subsequent bars.

I have done this in the past but its not working on the system I'm working
on right now - any suggestions?  I'd hate to have to use global variables
for every bar.
