Cleaning up Meshviewer example. That was too confusing to use and the code got too long for one file.

This example can be used to play around with material settings and watch the results.
Only the default non-shader materials are used in here.
You have two nodes to make it easier to see which difference your settings will make.
Additionally you have one lightscenenode and you can set the global ambient values.
You have a node witha mesh, one dynamic light and global ambient light to play around with.
