Re: [Cppqed-support] Timestep increase by Liouvillean now possible

[Andras V. <and...@ui...>]

P.S.:
O
f course, the present strategy increases the number of dpLimit-overshots,
which could be relieved by using
liouvilleanSuggestedDtTry=factor*dpLimit_/dpOverDt
with factor<1 instead of the present
liouvilleanSuggestedDtTry=dpLimit_/dpOverDt
(cf. MCWF_Trajectory.tcc:140)
But I do not think it be a problem.
