Detailed Description
"And" combination of different TriggerPullers.
Note that you need not make an AND combination directly, it is automatically done by the operator && function for TriggerPullers.
Example:
This creates a ref-counted ConditionAnd on the fly, and sets it as the activity's trigger.
A ConditionAnd will look for overlapping time intervals in the combined triggers; if tokenA triggers for (10,20), (20,30) and tokenB triggers for (8,12),(12,16), etc., the resulting trigger timing will be (10,12) (12,16), ...
Take care that both tokens are triggering approximately simultaneously; if tokenA is not triggering, all the triggering information in tokenB needs to be stored, leading to increased memory use.
When used in conjunction with a channel with event data, a monotonically increasing event-type triggering comes out. So if tokenB has (14,14), (27,27), (35,35); still with the triggering on tokenA as given above, the resulting trigger will be (14,14), (27,27), and the (35,35) comes out when tokenA has progressed to or beyond that point. I foresee no sensible scenario where this may be useful.

Friend fuction that will call the constructor to create an and condition with two trigger pullers.
This pulls only if both TriggerPullers have pulled. Useful for waiting on a consistent set of data from multiple stream channels.
