Parameters

[in]	a_pti	specifies the grid where the finder is defined
[in]	a_offset	particle index offset needed to access particle info
[in]	accelerator_lattice	a reference to the accelerator lattice at the refinement level
[in]	h_finder	The host level instance of the element finder that this is associated with
[in]	dts	vector containing the timestep sizes at all refinement levels
