Output bang if two bangs are received at the same time

This patch will output a bang if it receives a bang in both of its inputs simultaneously. A bang received by the right inlet will store a 1 in the integer object via the cold inlet. If the left inlet receives a bang before the end of the low priority queue, then a 1 will be outputted by the integer object to the select resulting in a bang from its left outlet. Otherwise, the deferlow object will bang the 0 into the integer object causing it to output a 0.
