Struct storing UpdateFlags for the 3 regions of a cell, \(K\), that is defined by the sign of a level set function, \(\psi\):
\[ N = \{x \in K : \psi(x) < 0 \}, \\ P = \{x \in K : \psi(x) > 0 \}, \\ S = \{x \in K : \psi(x) = 0 \}. \]
As in the QuadratureGenerator class, we refer to \(N\), \(P\) and \(S\) as the inside, outside, and surface region. RegionUpdateFlags is used to describe how the FEValues objects, which are created by NonMatching::FEValues, should be updated.
