Create a fault tree document and a fault tree.

myTreeDoc = safetyAnalysisMgr.newDocument("fault-tree");
myFaultTree = myTreeDoc.FaultTrees(1);

myTopGate = myFaultTree.Gates(1);
event1 = createEvent(myTopGate);
event2 = createEvent(myTopGate);
gate1 = createGate(myTopGate);
gate2 = createGate(myTopGate,Type="and");
gate22 = createGate(gate2);
event3 = createEvent(gate1);
event4 = createEvent(gate1);
event5 = createEvent(gate2);
event6 = createEvent(gate22);
event7 = createEvent(gate22);

Convert gate gate2 and its inputs into a fault tree.
