Version 6.0.1 released (21-Feb-2019)

This version (Git hash value 87b7556...) is mainly a maintenance release, serving to fix a few minor bugs. Among others, we fixed some inconsistencies wrt the order of some of the numerical propagation schemes. Unfortunately, this leads to minor issues with backward incompatibility. As of now, the choice of propagators is based on the local discretization error of the positions. In the table below, the third and fourth columns refer to objects of class "wave" and class "traj", respectively

time.propa	time.propa.order	quantum propagator	classical propagators
splitting	1	Lie-Trotter	March frog
	2	Strang-Marchuk	Leap frog
	3	not available	Beeman
	4	not available	Yoshida
differencing	2	second order differencing	Velocity Verlet
	3	not available	Stoermer Verlet ¹

¹ local discretization error of momenta differing: O(1)

Hence, the Strang-Marchuk operator splitting (a good choice for most quantum propagations) is selected by the following commands

time.propa = tmp.splitting;
time.propa.order = 2;
