** Internalize plan
- change order initiated update/cancel/crack/activate/report_state to
  use direct method calls
- need to watch out for reentrancy
- need to also report state externally 
- also want to separate active from non active orders in map to speed
  up look ups
- want to use direct references in orders to avoid lookups
- want to change how time is captured, the trace is too big to copy
  around
