Message:

delete intermediate theory-only plots after model evaluation, before adding current ones

this applies only to beta approximation, whereby plots such as beta(Q)
and S_eff(Q) may be removed between calculations. however, since it does
not affect behaviour otherwise, I am pushing to ESS_GUI to ensure no
later conflicts occur
