Functions
void	openswmm::input::handle_pollutants (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [POLLUTANTS] into PollutantData + pollutant_names.
void	openswmm::input::handle_landuses (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [LANDUSES] into LanduseData + landuse_names.
void	openswmm::input::handle_coverages (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [COVERAGES] — land use coverage fractions per subcatchment.
void	openswmm::input::handle_buildup (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [BUILDUP] — buildup functions per (landuse x pollutant).
void	openswmm::input::handle_washoff (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [WASHOFF] — washoff functions per (landuse x pollutant).
void	openswmm::input::handle_treatment (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [TREATMENT] — treatment expressions per (node x pollutant).
void	openswmm::input::handle_loadings (SimulationContext &ctx, const std::vector< std::string > &lines)
	Parse [LOADINGS] — initial pollutant buildup on subcatchments.
