Build issues on OS X 10.15

In a recent merge, bool getUseValidationSet() const; and bool getRandomiseTrainingOrder() const; were commented out inside GRT/CoreModules/MLBase.h.

Uncommenting them removed the make errors.

Was getting errors from fstream inside examples, so had to remove the whole directory for now(since I have to get this working for a project asap). That helped with the make continuing further.

Then finally got errors from all the cpp files inside tools for the #include <GRT/GRT.h>.
Replaced all with #include "../GRT/GRT.h" and that fixed the issue. But I think there was a warning above those includes for this anyway.

this is right. I uncommented like above. Instead of removing directory (?) i disabled the examples from being built in my cmake options, and replaced all includes like above too. Thanks for the pointers!
