"""This package contains infrastructure for solving differential equations within ``simframe``. The ``Integrator`` class
is the basic class that advances the simulation from snapshot to snapshot by executing one integration ``Instruction`` at
a time. Instructions contain a list of integration ``Scheme``. The ``schemes`` package contains pre-defined integration
schemes that are ready to use in ``simframe``."""
