--- **Core** - Define any or all conditions to be evaluated.
--
-- **Main Features:**
--
-- * Add arbitrary numbers of conditon functions
-- * Evaluate *any* or *all* conditions
--
-- ===
--
-- ## Example Missions:
--
-- Demo missions can be found on [github](https://github.com/FlightControl-Master/MOOSE_MISSIONS/tree/develop/Core/Condition).
