container for atomic derivative information.
An object which contains derivatives with respect to atomic position.
Notes on derivLists of EnsembleSimulations:
they share their derivList w/ their member() and subSim()
while other EnsembleMemberSimulations have their derivLists initialized,
these derivLists are generally not used.
init(simulation) - allocate and zero array corresponding to the specified
clear() - zero out all existing arrays.
get(simulation) - returns a cdsVector.CDSVector_Vec3 corresponding
to the derivatives of coordinates in the specified
