Configuring OpenGL

The OpenGL viewer (available in Nova_Examples/opengl) requires some symbolic links to be placed in the build directory for proper configuration. Run the following commands in order:

cd build/
ln -s ../Projects/Nova_Examples/opengl/example/nova.conf .
ln -s ../Projects/Nova_Examples/opengl/example/fonts/ .
ln -s ../Projects/Nova_Examples/opengl/plugins/Grid/shaders/ .

The viewer uses the modern GL pipeline and supports a plugin-based architecture, in the sense that every project can define its own plugin on how to view the generated data. While this does place the burden on the developer to write a separate plugin per project, it has the nice benefit of moving away from hard coding things in some master file.
