Compute the information in the given cells and faces. The cells are specified by the level and the index within the level (as given by CellIterator::level() and CellIterator::index(), in order to allow for different kinds of iterators, e.g. standard DoFHandler, multigrid, etc.) on a fixed Triangulation. In addition, a mapping and several 1d quadrature formulas are given.

Internal function to compute the geometry for the case the mapping is a MappingQ and a single quadrature formula per slot (non-hp-case) is used. This method computes all data from the underlying cell quadrature points using the fast operator evaluation techniques from the matrix-free framework itself, i.e., it uses a polynomial description of the cell geometry (that is computed in a first step) and then computes all Jacobians and normal vectors based on this information. This optimized approach is much faster than going through FEValues and FEFaceValues, especially when several different quadrature formulas are involved, and consumes less memory.

Stores whether a face (and both cells adjacent to the face) is Cartesian (face type 0), whether it represents an affine situation (face type 1), whether it is a flat face where the normal vector is the same throughout the face (face type 2), or is general (face type 3).
