Global basis for given pre-basis.
This class implements the interface of a global basis using the details from a given pre-basis. Hence it serves as an example for this interface.
If you want to implement your own global basis, it may be better to implement a pre-basis instead. On the one hand this needs less boiler-plate code. On the other hand it makes your implementation composable and thus much more flexible. That is, you can reuse your pre-basis as one part in a larger product space by plugging it e.g. into a CompositePreBasis of PowerPreBasis. The actual global basis for your FooPreBasis is then obtained by using DefaultGlobalBasis<FooPreBasis>.
