Joshua Harlow 5ca61f956e Add a directed graph type (new types module) 
Most of the utility graph functions we have can
be connected to a directed graph class that itself
derives (and adds on to) the networkx base class.

Doing this allows for functionality that isn't exposed
in networkx to be exposed in our subclass (which is a
useful pattern to have).

It also makes it possible (if ever needed) to replace
the networkx usage in taskflow with something else if
this ever becomes a major request.

Utils

There are various helper utils that are part of taskflows internal usage (and external/public usage of these helpers should be kept to a minimum as these utility functions may be altered more often in the future).

External usage

The following classes and modules are recommended for external usage:

taskflow.utils.misc.Failure

taskflow.utils.eventlet_utils.GreenExecutor

taskflow.utils.persistence_utils.temporary_log_book

taskflow.utils.persistence_utils.temporary_flow_detail

taskflow.utils.persistence_utils.pformat
