 Molecular simulation techniques play a very important role in our quest to understand and predict the properties, structure, and function of molecular systems, and are a key tool as we seek to enable predictive molecular design.
 Simulation methods are extremely useful for studying the structure and dynamics of complex systems that are too complicated for pen and paper theory, helping interpret experimental data in terms of molecular motions.
-Additionally, they are increasing used for quantitative prediction of properties of use in molecular design and other applications~\cite{Nussinov2014,Towns2014,Kirchmair2015,Sresht2017,Bottaro2018}.

 The basic idea of any molecular simulation method is straightforward; a particle-based description of the system under investigation is constructed and then the system is propagated by either deterministic or probabilistic rules to generate a trajectory describing its evolution over the course of the simulation~\cite{Frenkel:2001:,LeachBook}.
 Relevant properties can be calculated for each ``snapshot'' (a stored configuration of the system, also called a ``frame'') and averaged over the the entire trajectory to compute estimates of desired properties.
