Max Brunsfeld	ad619d95f6	Add 'extra' field to symbol metadata ... This stores whether a symbol is only ever used as a ubiquitous token. This will allow ubiquitous nodes to be reused more effectively: if they are always ubiquitous, then they can be reused immediately, and otherwise, they must be broken down in case they need to be used structurally.	2015-12-02 15:10:24 -08:00
