Description: Computing fundamental classes of strata of differentials using the package admcycles

Below we compute the divisor class given by the closure $\overline{\mathcal{H}}_2^1(2) \subset \overline{\mathcal{M}}_{2,1}$ of the locus
${\mathcal{H}}_2^1(2) = {\{(C,p) : \exists \text{ differential $\eta$ on $C$ with double zero at $p$} \}} \subset {\mathcal{M}}_{2,1}$
