"""
An IMPLY Gate is a logic gate in boolean algebra which results to 1 if
either input 1 is 0, or if input 1 is 1, then the output is 1 only if input 2 is 1.
It is true if input 1 implies input 2.
Following is the truth table of an IMPLY Gate:
------------------------------
| Input 1 | Input 2 | Output |
------------------------------
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
------------------------------
