Message:

BondVectors now return subset of BondVectors for a given atom.

• functionality extracted from ForceAnnealing::annealWithBondgraph().
• also the mapped_t type is now kept up-to-date internally as we need it for returning the subset efficiently over a number of atoms, e.g. all in the given range.
• also moved a few simple implementations over to _impl module.

File:

• src/Dynamics/BondVectors.hpp (modified) (3 diffs)
