1. add ExecNode and StreamRxecOrderRecorer
2. add json format and json dump for stream exec order
3. add stream exec order api
4. add in CMakeLists

1. add validation for directory and filename
2. refactor the file operations about path
3. add in CMakeLists
4. add logger in nn_ops

The basic idea is: exploits data dependency to control the execution order
of side-effect operations, and keep the semantics of ANF unchanged.

The ControlDepend primitive is removed and there are two primitives added:

1. UpdateState:
```
  a = Assign(para, value)
```
became:
```
  a = Assign(para, value, u)
  u = UpdateState(u, a)
```

2. Load:
```
  x = Add(para, value)
```
became:
```
  p = Load(para, u)
  x = Add(p, value)
  u = UpdateState(u, p)
```
