Roles consumed by OneH objects to be used in a Photonic calculation. Basic scheme for the calculation of one Haydock coefficient and one Haydock state at a time. See also the specific implementations.
Create a new Photonic::...::OneH object with GeometryG0 $g and optional smallness parameter $s.
A Photonic::Geometry object defining the geometry of the system, the charateristic function and the direction of the G=0 vector. Should be given in the initializer.

Accesors handled by geometry (see Photonic::Roles::Geometry)
A small number used as tolerance to end the iteration. Small negative b^2 coefficients are taken to be zero.

The n-1-th, n-th and n+1-th Haydock states
The n-th Haydock coefficient a
current_b2 next_b2 current_b next_b
The n-th and n+1-th b^2 and b Haydock coefficients
Number of completed iterations
Performs a single Haydock iteration and updates current_a, next_b, next_b2, next_state, shifting the current values where necessary. Returns 0 when unable to continue iterating.
