0.10.0 (2020-08-25)

• Fixed several race conditions that could cause the TaskGraph object to
  hang on an otherwise ordinary termination.
• Changed logging level to "INFO" on cases where the taskgraph was not
  precalculated since it's an expected path of execution in TaskGraph.
• Adding a hardlink_allowed parameter to add_task that allows the
  attempt to hardlink a file in a case where a copy_artifact=True may
  permit one. This will save on disk space as well as computation time
  if large files are not needed to copy.
• Adding a store_result flag to add_task that conditionally stores
  the func result in the database for later .get. This was added to
  guard against return types that were not picklable and would otherwise
  cause an exception when being executed normally.
• Fixed issue that would cause the logger thread to continue reporting status
  after all tasks were complete and the graph was closed.
