Zachary Snow 84edbae503 preliminary scoped errors with approximate source location 
- scoped traversals can now raise errors which contain the path of the

  trace comments, if available
- initially, this new error messaging has only been added for the
  illegal size cast checks in the TypeOf and Cast conversions
- error suite tests can provide a verbose mode expected source location
