Create HW2_Event_Profiler.py

Script scans SP500 for desired events and creates a graphic summary of all events within the designated time series. This script is modified to scan for event in which the price has fallen below a given price. The commented out lines were left in the code to enable adaptation of the code for a percentage price change vs the SP500. This script borrows heavily from the QSTK - Event Profiler Tutorial. In addition, it contains code that will look for and remove bad symbols in your list of symbols. This code was found in another QSTK tutorial and adapted for this script.
