BlockTrigger is an event trigger which calls a block to check events. The trigger fires if the block returns true when called with the event as the only parameter.
Initialize a new instance of BlockTrigger with the given block. The block should take only 1 parameter, the event, and return true for matching events.
|&block:||The block to pass events to. (Proc, required)|
