Detailed Description

template<class Monitor>
class swarm::cpu::mvs_cpu< Monitor >

CPU implementation of mixed variables symplectic propagator: template<class Monitor> EXPERIMENTAL: This class is not thoroughly tested.

This is used as a reference implementation to test the GPU implementation of the mvs integrator

This integrator can be used as an example of CPU integrator

Todo:
make Gravitation class a template parameter: template<class Monitor, class GravClass>
