ANSI C++ changes revisited

[Will Schroeder]

Hi Folks-

Remember the changes I made yesterday with regard to ANSI C++ ? Well they're already obsolete. Bill Hoffman discovered a better way to do it late last night (and thanks to the VXL code).

What we did is to create new typedefs like "typedef std::ostream vtkOstream".

What we can do instead is: "using std::ostream;"

Fortunately, all is not lost, we still retain the changes due to include files, and creation of the vtkSystemIncludes.h, etc.

The implications are as follows: instead of having PrintSelf(vtkOstream...) we have PrintSelf(ostream...) like before, except this time if ANSI C++ is turned on, ostream is really std::ostream because of the "using std::ostream'". This means code writers don't have to worry about these special types.

Much humbler I'll be checking the changes in shortly (unless someone has a good reason not to!)

Will
