Enable multiple bindung models within one particle type

[AntoniaBerger]

Different components can bind to the stationary phase with different mechanism.
Currently, it is not possible to capture this effect using different binding models in one particle type.

Is this something we want to have? This would require sanity checks, e.g. req. bindings could contradict each other.
What do you think @lieres ?

[lieres]

It is certainly something I would like to have. As with reactions, several binding mechanisms can be active at the same time. However, we need to develop a good concept for specifying which binding mechanism involves which (of several) binding sites.

I see, thanks. If it's always with distinct binding sites, then there should always be a solution.
