Child threads are not sending data at the expected time for a larger cycle time

[Dan Dexter]

HLA data going to and from Trick child threads that have a difference cycle rate than the main thread are sending data at the wrong time. The issue is that data is being sent on the same main thread frame boundary and not at the end of the child thread frame.

Data from the child thread should be sent on the main thread frame that corresponds to the end of the child thread frame.

Child |              |   child thread data cycle: 3
 Main |    |    |    |   main thread data cycle:  1
 Time 0    1    2    3
                  ^-- Check for child thread sending in main thread frame here.
                ^-- (child_cycle - main_cycle) = ( 3 - 1 )
