Subject: [Repast-interest] Suggestion to prevent wrong use of
addProjection()

Hi,

I didn't realize that the GridFactory not only create the Grid but also
add it to the context.
And so I was wrong using a context.addProjection(grid) after having
created a grid through the factory.

The result of this operation was that every object added to the context
was added 2 times into the grid (at different positions), and of course
that led to unexpected behaviors ...

Having spent a couple of hours of debbuging to find out my mistake, I
think it would be nice (for those that can go through the same mistake,
I won't do it again ;-)) to raise an exception when adding a projection
which has the same name than an existing one.

John
