+    a Routine can be given different combinations of the above, but business logic may validate 
+    these at Routine construction
+
+    For example, a Routine could have the following characteristics
+    - DelayedStart (so it skips the first iteration)
+    - ScheduledStart(DateTime<Local>) - With a Start Date-Time for the first iteration to trigger
+    - LoopDuration(Duration) - How long to wait between iterations
+
+    The above without any other thresholds would loop infinitely with the above characteristics 
+
+    Another example,
+    - LoopDuration(Duration) - How long to wait between iterations
+    - MaxTimeThreshold(DateTime<Local>)
+    - MaxIterations(i64) 
+
+    The above has thresholds , so if either are reached, it would abort/cancel or stop . Since there is no 
+    ScheduledStart, the routine would have to be started manually elsewhere
+
+    Another example , 
+    - (no RoutineAttr)
+
+    The above would only run once, and only when the Start() is called
