"""
An OR Gate is a logic gate in boolean algebra which results to 1 (True) if any of the
inputs is 1, and 0 (False) otherwise.

Following is the truth table of an OR Gate:
------------------------------
| Input 1 | Input 2 | Output |
------------------------------
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
------------------------------
