%description
Builds and runs 'c++' code for classes that encapsulate state space model,
particle filtering algorithm pairs. Algorithms include the Bootstrap
Filter from Gordon et al. (1993) <doi:10.1049/ip-f-2.1993.0015>, the
generic SISR filter, the Auxiliary Particle Filter from Pitt et al (1999)
<doi:10.2307/2670179>, and a variety of Rao-Blackwellized particle filters
inspired by Andrieu et al. (2002) <doi:10.1111/1467-9868.00363>. For more
details on the 'c++' library 'pf', see Brown (2020)
<doi:10.21105/joss.02599>.
