Does file OutGrammar.h have '#include <string>' in it?

Also type std::string is template. Some compilers (particularly in  
the past) may cause error if there has been no use of the type before  
used as a pointer, due to poor template expansion. So then one try yo  
put in a declaration of some sort.
