to a little figure out what Guido had done & why -- but there is a neat saving of force evaluations across the nesting time boundary making use of linearity of the leapP in dt. I cleaned up the printing, reduced the volume of code, in the process sharing printing between all integrators. Placed an assert that the total integration time for all integrators must match at end of trajectory. Have now verified e-dH = 1 for nested integrators in Wilson/Wilson runs with both Omelyan and with Leapfrog so substantial confidence gained.
