Zachary Snow 6ee558b6b9 initial pass improving decl parsing error messages 
- all decl tokens are given an accurate starting position
- key grammar productions return token positions to facilitate the above
- helpers for standardized parse error generation
- replaced annoying pattern-matching type argument restrictions
- moving away from dumping raw decl tokens in error messages

Zachary Snow ff0c7b026c properly distinguish nets and variables internally

- support var declaration type prefix for all data types
- support var as lone type shorthand
- refactor AST representation of strengths
- traversal helpers for treating nets as variables
- use decl traversals where appropriate

  mark where injected items will end up in advance
