"""
An NIMPLY Gate is a logic gate in boolean algebra which results to 0 if
either input 1 is 0, or if input 1 is 1, then it is 0 only if input 2 is 1.
It is false if input 1 implies input 2. It is the negated form of imply

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