[Scip] nlpi and two pub_expression.h files

[Sebastian Ruther]

  Hello

I upgraded to Scip 2.0.0 and it caused a few problems for me. The 
biggest is: why are there two pub_expression.h, one in the regular scip 
src directory and one in the nlpi directory?
I use Visual Studio 2010 on Windows 7 and have all Scip files sitting in 
different projects. The pub_expression.h files then cause linkage errors.
I don't want to use the nlpi at all. Isn't there a way to get rid of it? 
What else can I do to resolve this conflict?

Regards,
Sebastian
