Queue Test simulation and latest code.

Queue simulation code is uploaded as a part of eclipse project
QueueTest.
In the \dev\Code folder, latest code for the following modules is
present :
1. eventqueue
2. reportgenerator
3. garbagecollector
Rule Engine code is also there but it is the one that I was using . I
believe it has been completely changed into ruleengine-runtime. The only
thing to be copied from this rule engine code to the runtime code is the
iterator calling part.
