Render more than one state var and unit of information

[d2fong]

Only up to one state var and one unit of information is rendered per node.

In conjunction with the scaling node width, we can render more (within reason)

Regulation of TP53 Activity through Methylation | Reactome for TTC5 which should show two phosphorylation state variables (203, 221) but only shows first.

Another odd side-effect of this issue is that the state var/unit of information displayed is non-deterministic:

e.g. This biofactoid doc the GCLM state variable shown can be either demethylate or active:
