or_gate.py

"""
An OR Gate is a logic gate in boolean algebra which results to 0 (False) if both the
inputs are 0, and 1 (True) otherwise.
Following is the truth table of an AND Gate:
    ------------------------------
    | Input 1 | Input 2 | Output |
    ------------------------------
    |    0    |    0    |    0   |
    |    0    |    1    |    1   |
    |    1    |    0    |    1   |
    |    1    |    1    |    1   |
