class  TopologicalCharge
 Solely calculates the topological charge as given by,

\[ q(n_e) = \frac{1}{32\pi^2} \sum_{n \in N^3} \epsilon_{\mu\nu\rho\sigma} \mathrm{tr}\big[F_{\mu\nu}(n)F_{\rho\sigma}(n)\big], \]

where \(n_e\) is the position in the lattice in Euclidean time. \(F_{\nu\mu}\) is the clover. More...
