added timing policy to std eng conf
added async background vi and launch/shutdown from async module in tbd core
added most of the async launching code, still working on integrating into the engine
a few tweaks: add clear error to background process, fix shutdown code to handle different types (rt fifo instead of notifier), added error broadcast to background process
added input/output/process/error to std eng main loop
added safe state functionality
completed initialization, feature complete
tested and confirmed functionality of error handling, startup, shutdown.
safe state modified to become a wait state, sort of like paused. async is now fully tested for input and output. **PROCESS REQUIRES WORK** at the very least I know safe state doesn't work as expected.
added test module (based on CVT)
changed init to calculate exec time based on standard engine loop period
Merge branch 'feature/autoparallel' into develop
