Detailed Description

template<int dim, int spacedim = dim> struct FESystem< dim, spacedim >::BaseOffsets

Computing values on a cell requires copying values between the FEValuesImplementation::FiniteElementRelatedData objects owned by the present object and its subelements. The indexing for this is fairly complicated since each shape function in the nonprimitive base element may have a different number of nonzero components (e.g., a Taylor-Hood pair base element): we also need offsets into both the base element and present element's arrays. To this end, we will create a table with all the necessary information for each shape function in the nonprimitive base element.
