Public Types
using	allocator_type = Allocator_
	the allocator its sets and indices come from

Public Member Functions
	Step (ParticleSetType const &recorded, Allocator_ const &allocator={})
	A copy of recorded in storage from allocator, with the recorded particles as the smoothed ones until smooth() runs, and room for a parent per particle.
	Step (Step const &other, Allocator_ const &allocator)
	Copies other into storage from allocator.
	Step (Step &&other, Allocator_ const &allocator)
	Moves other into storage from allocator, taking its storage when the allocators are equal.
	Step (Step const &)=default
	copies the sets and the parents
	Step (Step &&)=default
	moves the sets and the parents
Step &	operator= (Step const &)=default
	Copies into this step's storage.
Step &	operator= (Step &&)=default
	Takes the other step's storage, as the members' do.

Public Attributes
ParticleSetType	particles
	The particles as push() recorded them, before the step's prediction.
ParticleSetType	smoothed
	\( p(x_k \mid z_{1:N}) \) for the step's \( x_k \), as of the last smooth(): the traced states with the latest weights; a copy of particles until then
IndexBuffer	parents
	If resampled, particle i here descends from particle parents[i] of the step before; otherwise from particle i, and parents is unused.
bool	resampled = false
	whether a resample fell between the step before and this one
