Renderers
Most of the renderers are implemented in the pyfeyn2.render module.
The once based on latex are in pyfeyn2.render.latex.
They offer the function pyfeyn2.render.latex.LatexRender.get_src_diag() to get the latex source for rendering this diagram or the whole latex source via pyfeyn2.render.latex.LatexRender.get_src().
Some more specialized renderers offer their source through different functions like pyfeyn2.render.dot.DotRender.get_src_dot().
