 Representation of a particle with a state. It has four fields:
 - `dir::ParticleDirection`: The direction of the particle, `QEDbase.Incoming()` or `QEDbase.Outgoing()`.
-- `species::AbstractParticleType`: The species of the particle, `QEDbase.Electron()`, `QEDbase.Positron()` etc..
+- `species::AbstractParticleType`: The species of the particle, `QEDbase.Electron()`, `QEDbase.Positron()` etc.
 - `mom::AbstractFourMomentum`: The momentum of the particle.
-- `spin_or_pol::AbstractSpinOrPolarization`: The spin or polarization of the particle, `QEDbase.SpinUp()`, `QEDbase.PolX() etc.. Can only use spins with fermions and polarizations with bosons.
