Added unit tests to test code in def/ module. Currently, AverageNodePowerHistory(...) assumes that the DRAM power readings are being monitored. In addition, it also assumes that the host servers are dual socket machines. However, this assumption might not always hold true. Thus, added a TODO to fix this.
