Explanation/Tutorial on effective dimension in documentation

[ParadaCarleton]

Effective dimension is a very important concept in QMC; it's necessary to understand what points you should use and how to . We should probably create a tutorial explaining them. (Otherwise people are likely to assume QMC points are a drop-in replacement for Monte Carlo points that can be used without additional thought. I know I did before learning more about them :sweat_smile: )

That would be fantastic to add. I mean right now the package has 0 tutorials, so 1 tutorial would be infinity times better.
