 Dataflow Oriented Robotic Architecture

+## Python API Design
+
+The Python API is probably going to look as follows:
+```python
+@register
+async def function_name(state: DoraState, message: DoraMessage):
+    return outputs
+``` 
+
+The philosophy is to use async function as primary instance to:
+- Mitigate the risk of running undafe data mutations.
+- Managing several run at the same time with timeout / deadline capabilities
+- Using Tokio Spawn to avoid thread locks on CPU bound runs.
