Summary: Fixed Ganglia Metric Mode, Added Serial_control.py

Details: Ganglia Metric mode was sending the same data to each strip. Fix was to move setting an index variable to 0 out completely out of the loops that send data. Additionally, consolidated the send data to serial with zero padding function into a single file, serial_control.py for easier maintainability. Finally, updated README by starting "How to Run" section.

Files Changed:
led_init.py
led_control.py
gangliacomm.py
serial_control.py
README.md
