Made a few small error checking tweaks to basisvariance. These should
not change between the last version.
Adding some debugging tools
more debugging, checking out different branch
Found the error with the electrostatics, the <P2> and the <P^2> label
were overwriting each other. This caused incorret variances.

Attractive variance is small and VERY noisy. Causes many variances to
be negative, probably not an issue though as we expect the variance of
decoupling attractive in the presence of a repulsive core to be all but
non-exsistant.
