+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   |
+    ------------------------------
