The float/int math is working.
Major refactoring of references and scopes.
Refactoring blocks to be simpler and more universal.
Getting close to getting this phase of features working.  Considering switching to node pointers instead of ids to allow for unregistered nodes.
Got vector math sort of working.  Going to refactor references from ids to node objects.
Refactored node references and some other smaller things.  Lots of performance improvements.
Adding if statements.
Moving if from being a statement to an expression.
