+
+Write a function expect that helps developers test their code. 
+It should take in any value val and return an object with the following two functions.
+
+toBe(val) accepts another value and returns true if the two values === each other.
+ If they are not equal, it should throw an error "Not Equal".
+
+
+notToBe(val) accepts another value and returns true if the two values !== each other.
+ If they are equal, it should throw an error "Equal".
+ 
+
+Example 1:
+
+Input: func = () => expect(5).toBe(5)
+Output: {"value": true}
