Introduction
============

Spatial solitons are nonlinear localized states that keep their form during propagation due to the balance between diffraction and self-induced nonlinear potential [@Stegeman_science_1999]. Recently, there has been a lot of interest in a generalized type of spatial solitons, the so-called azimuthons. These are azimuthally modulated beams, that exhibit steady angular rotation upon propagation [@desyatnikov_prl_2005]. They can be considered
