VAR_2SITE	Most efficient algorithm: the two-site variance as proposed in Hubig, Haegeman, Schollwöck (PRB 97, 2018), arXiv:1711.01104.
VAR_HSQ	Full variance of the energy: $\langle H^2\rangle-\langle H\rangle^2$ .
NORM_TEST	Overlap to state from previous calculation. Not a very good measure.
VAR_FULL	This computes the norm of the full resolvent: $\left\Vert H \|\Psi\rangle - E \|\Psi\rangle \right\Vert$ .
