Detailed Description

Integrator of conjugate momenta for given link variables.

This class updates conjugate momenta by force terms provided by action classes. it contains a list of actions that belong to a level of nested integrators. The value of force is cached in order to re-use it for the next half-step in multi-level integrator. cache should be invalidated when the link variable is updated through the call of invalidate_cache() method.
