Map global indexes to local indexes E.g.

g2l[i] is the position of atom i in the array passed from the MD engine. Called "global to local" since originally it was used to map global indexes to local ones used in domain decomposition. However, it is now also used for the NAMD-like interface, where only a small number of atoms is passed to plumed.

bool PLMD::Atoms::zeroallforces

private

if set to true, all the forces in the global array are zeroes at every step.

It should not be necessary in general, but it is for actions accessing to modifyGlobalForce() (e.g. FIT_TO_TEMPLATE).
