Well, you just made the type D, so you can make Array{D,n} or anything else
like that. The Base types are not special in Julia, anywhere you can use a
type, you can use your own.
You can create an empty form of your type via dinstance = D(). You can then
add to it by setting dinstance.data = someMatrix; dinstance.header = "hi!".
In fact, you can make a whole array of empty D's by Darr = [D() for i in
1:N] and then set the fields in a loop by Darr[i].data = someMatrix. You
might want to read the documentation on type for more details.
If you need the fields to be mutable, you can make one of the fields in the
type be a dictionary and use that, or you can use a cell array (I think
these may be deprecated?)
