Base class for the hp::FE*Values classes, storing the data that is common to them. The main task of this class is to provide a table where for every combination of finite element, mapping, and quadrature object from their corresponding collection objects there is a matching FEValues, FEFaceValues, or FESubfaceValues object. To make things more efficient, however, these FE*Values objects are only created once requested (lazy allocation).
The first template parameter denotes the space dimension we are in, the second the dimensionality of the object that we integrate on, i.e. for usual hp::FEValues it is equal to the first one, while for face integration it is one less. The third template parameter indicates the type of underlying non-hp FE*Values base type, i.e. it could either be FEValues, FEFaceValues, or FESubfaceValues.

Constructor. This constructor is equivalent to the other one except that it makes the object use a \(Q_1\) mapping (i.e., an object of type MappingQGeneric(1)) implicitly.

Return a reference to the FEValues object selected by the last call to select_fe_values(). select_fe_values() in turn is called when you called the reinit function of the hp::FE*Values class the last time.

Select a FEValues object suitable for the given FE, quadrature, and mapping indices. If such an object doesn't yet exist, create one.
The function returns a writable reference so that derived classes can also reinit() the selected FEValues object.

A table in which we store pointers to fe_values objects for different finite element, mapping, and quadrature objects from our collection. The first index indicates the index of the finite element within the fe_collection, the second the index of the mapping within the mapping collection, and the last one the index of the quadrature formula within the q_collection.
Initially, all entries have zero pointers, and we will allocate them lazily as needed in select_fe_values().
