Makefile

How to run:
	1. make 
	
	2. part1: ./part1
	   part2: ./part2
	   part3: ./part3 [commands_file]
	   part4: ./part4 [commands_file]
	   part5: ./part5 [commands_file]

For testfiles, to create topic, index starting from 0...n
For file for the publisher thread, topic ID should start from 1...n

Part1 - it compiles it and work correctly (Checked it on VM machine arch linux)
Part2 - it compiles it and work correctly (Chekced it on VM machine arch linux)
Part3 - it compiles it and work correctly (Chekced it on VM machine arch linux)
Part4 - it compiles it and work correctly (Chekced it on VM machine arch linux)
Part5 - it compiles it and work correctly (Chekced it on VM machine arch linux)

For part1, to pass the valgrind test using Roscoe's bq_test.c I have to set
	queue->buffer[RoundIDToBufferIndex(queue->size, queue->tail)] = NULL;

but, to pass the valgrind test using my testcases and other parts, I have to set
	free(queue->buffer[RoundIDToBufferIndex(queue->size, queue->tail)]);

For part4/5 I give clean up thread to sleep for 4 seconds to give
publisher/subscriber little time to work. Otherwise, base on the delta time,
subscriber do not have time to access the item.

Also, for part4/5, normal usage has no problem with sleeptime,
but when I use valgrind, then sometimes cleanup thread came in faster than the 
subscriber, so subscriber reads id+1 element.

For pub/sub threads, Since my new test file have little odd sleeping time, getitem failed.
So I gave them a maximum 6 tries when queue is EMPTY, FULL and Getitem Failed. so that pub/sub/cleanup do the work.

After 6 tries, it frees all the alloc memory and exit the thread.

./valtest 1,2,3,4,5 has no memeory leaks in any circumstances.
